+ Revert "Bug #6247: Fix build on Cygwin"
+
+ libtool requires the '-no-undefined' flag in order to create shared
+ libraries on PE/COFF platforms (Cygwin/MinGW); on other platforms this
+ flag has no effect.
+
+ The problem with libXfont is that PE weak symbols do not behave exactly
+ as they do on ELF platforms. Since PE binaries (both executables and
+ libraries) must have all symbols resolved at link time, there is no way
+ for the real symbols in xserver to "displace" those in libXfont at
+ runtime, so the result is that libXfont uses its stubs, which do
+ nothing, and xserver ends up unable to find its fonts.
+
+ Solving this will require either significant changes to libXfont or some
+ major improvement to the toolchain to handle this case. Until that
+ happens, removing '-no-undefined' will result in a static-only library
+ on these platforms, which is the only currently working solution.

+
+ Build fix for platforms which don't have weak linkage
+
+ Since we fix this by removing the serverGeneration symbol, assuming
+ an external definition will be provided, this means on Windows libXfont
+ can only be built as a static library (since PE shared libraries cannot
+ contain undefined symbols). This produces a libXfont which might only
+ be useful to the xserver, but the only other users we might care about
+ are xfs, which is obsolete, and bdftopcf, which fortunately doesn't
+ pull in any objects which reference serverGeneration from libXfont.

+ Use one single function to register fpe functions
+
+ X server doesn't need to understand fpe internals, so let it transparent
+ turning all registration functions in a single one. For that, fill the already

+
+ Some X servers don't want font server support, so this patch also sets font

+ libXfont ansification and removal of xf86_ansic.h dependency
+
+ Basically the code is now compiled as if FONTMODULE was never defined,
+ but also removed some "magic" defining _XOPEN_SOURCE before including
+ math.h.
+ Also removed some #if 0'ed code instead of fixing prototypes inside
+ the "dead code".
+ Changes to spdo_prv.h were due to defines like:
+ <hash>define foo() sp_foo()
+ that would not compile with the ansification in the format:
+ type foo(void)
+ due to the macro receiving "void" as an argument.

+ Always scan catalogue dirs at startup, even if their mtime < 0
+
+ Works around bug in VMWare that caused the Solaris kernel to fail to read
+ the time-of-day chip on boot, and start with a time < 0 (i.e. back to the
+ 1960's) - when the system was then installed from this mode, Xorg wouldn't
+ start after reboot, since the mtime would be < 0 and the catalogue dir was
+ then skipped as not changed since reading at the 0 initially set in the
+ cat->mtime.

+ Remove side effects from BuiltinReadDirectory()
+
+ The first time BuiltinReadDirectory() is called,
+ save the content of builtin_dir and builtin_alias,
+ before calling FontFileAddFontFile(), because that fonction
+ will modify those.
+
+ Then, in subsequent calls to BuiltinReadDirectory(), restore
+ builtin_dir and builtin_alias so that the side effect incurred
+ by the first call disappears.

+
+ Add a new 'catalogue' FPE, which takes font paths from symlinks in a dir.
+
+ This patch adds a new FPE type, which will match font path elements of the
+ form
+
+ catalogue:<dir>
+
+ The dir specified after the catalogue: prefix will be scanned for symlinks
+ and each symlink destination will be added as a local fontfile FPE.
+ The symlink can be suffixed by attributes, such as 'unscaled', which
+ will be passed through to the underlying fontfile FPE. Except the new
+ attribute 'pri' which will be used for ordering the fontfile FPEs.
+
+ An example configuration:
+
+ 75dpi:unscaled:pri=20 -> /usr/share/X11/fonts/75dpi
+ ghostscript:pri=60 -> /usr/share/fonts/default/ghostscript
+ misc:unscaled:pri=10 -> /usr/share/X11/fonts/misc
+ type1:pri=40 -> /usr/share/X11/fonts/Type1
+ type1:pri=50 -> /usr/share/fonts/default/Type1
+
+ will add /usr/share/X11/fonts/misc as the first FPE with the attribute
+ 'unscaled', second FPE will be /usr/share/X11/fonts/75dpi, also with
+ the attribute unscaled etc. This is functionally equivalent to setting
+ the following font path:
+
+ /usr/share/X11/fonts/misc:unscaled,
+ /usr/share/X11/fonts/75dpi:unscaled,
+ /usr/share/X11/fonts/Type1,
+ /usr/share/fonts/default/Type1,
+ /usr/share/fonts/default/ghostscript
+
+ The motivation is to let font packages add a symlink to the new font
+ directory they provide instead of rewriting either the Xorg config file
+ or the xfs config file.

+libXfont provides the core of the legacy X11 font system, handling the
+index files (fonts.dir, fonts.alias, fonts.scale), the various font file
+formats, and rasterizing them. It is used by the X servers, the
+X Font Server (xfs), and some font utilities (bdftopcf for instance),
+but should not be used by normal X11 clients. X11 clients access fonts
+via either the new API's in libXft, or the legacy API's in libX11.

+Quick Guide To Patching This Package For The Impatient
+------------------------------------------------------
+
+1. Make sure you have quilt installed
+2. Unpack the package as usual with "dpkg-source -x"
+3. Run the "patch" target in debian/rules
+4. Create a new patch with "quilt new" (see quilt(1))
+5. Edit all the files you want to include in the patch with "quilt edit"
+ (see quilt(1)).
+6. Write the patch with "quilt refresh" (see quilt(1))
+7. Run the "clean" target in debian/rules
+
+Alternatively, instead of using quilt directly, you can drop the patch in to
+debian/patches and add the name of the patch to debian/patches/series.
+
+------------------------------------
+Guide To The X Strike Force Packages
+------------------------------------
+
+The X Strike Force team maintains X packages in git repositories on
+git.debian.org in the pkg-xorg subdirectory. Most upstream packages
+are actually maintained in git repositories as well, so they often
+just need to be pulled into git.debian.org in a "upstream-*" branch.
+Otherwise, the upstream sources are manually installed in the Debian
+git repository.
+
+The .orig.tar.gz upstream source file could be generated this
+"upstream-*" branch in the Debian git repository but it is actually
+copied from upstream tarballs directly.
+
+Due to X.org being highly modular, packaging all X.org applications
+as their own independent packages would have created too many Debian
+packages. For this reason, some X.org applications have been grouped
+into larger packages: xutils, xutils-dev, x11-apps, x11-session-utils,
+x11-utils, x11-xfs-utils, x11-xkb-utils, x11-xserver-utils.
+Most packages, including the X.org server itself and all libraries
+and drivers are, however maintained independently.
+
+The Debian packaging is added by creating the "debian-*" git branch
+which contains the aforementioned "upstream-*" branch plus the debian/
+repository files.
+When a patch has to be applied to the Debian package, two solutions
+are involved:
+* If the patch is available in one of the upstream branches, it
+ may be git'cherry-picked into the Debian repository. In this
+ case, it appears directly in the .diff.gz.
+* Otherwise, the patch is added to debian/patches/ which is managed
+ with quilt as documented in /usr/share/doc/quilt/README.source.
+
+quilt is actually invoked by the Debian X packaging through a larger
+set of scripts called XSFBS. XSFBS brings some other X specific
+features such as managing dependencies and conflicts due to the video
+and input driver ABIs.
+XSFBS itself is maintained in a separate repository at
+ git://git.debian.org/pkg-xorg/xsfbs.git
+and it is pulled inside the other Debian X repositories when needed.
+
+The XSFBS patching system requires a build dependency on quilt. Also
+a dependency on $(STAMP_DIR)/patch has to be added to debian/rules
+so that the XSFBS patching occurs before the actual build. So the
+very first target of the build (likely the one running autoreconf)
+should depend on $(STAMP_DIR)/patch. It should also not depend on
+anything so that parallel builds are correctly supported (nothing
+should probably run while patching is being done). And finally, the
+clean target should depend on the xsfclean target so that patches
+are unapplied on clean.
+
+When the upstream sources contain some DFSG-nonfree files, they are
+listed in text files in debian/prune/ in the "debian-*" branch of
+the Debian repository. XSFBS' scripts then take care of removing
+these listed files during the build so as to generate a modified
+DFSG-free .orig.tar.gz tarball.

+ <title>
+ Requirements for the Font library
+ </title>
+
+ <para>
+ To avoid miles of duplicate code in the X server, the font server
+ and the various font manipulation tools, the font library should
+ provide interfaces appropriate for all of these tasks. In
+ particular, the X server and font server should be able to both
+ use the library to access disk based fonts, and to communicate
+ with a font server. By providing a general library, we hoped to
+ avoid duplicating code between the X server and font server.
+ </para>
+
+ <para>
+ Another requirement is that the X server (or even a font server)
+ be able to continue servicing requests from other clients while
+ awaiting a response from the font server on behalf of one client.
+ This is the strongest requirement placed on the font library, and
+ has warped the design in curious ways. Because both the X server
+ and font server are single threaded, the font library must not
+ suspend internally, rather it returns an indication of suspension
+ to the application which continues processing other things, until
+ the font data is ready, at which time it restarts the suspended
+ request.
+ </para>
+
+ <para>
+ Because the code for reading and manipulating bitmap font data is
+ used by the font applications <command>mkfontdir</command> and
+ <command>bdftopcf</command>, the font library includes
+ bitmap-font specific interfaces which those applications use,
+ instead of the more general interfaces used by the X and font
+ servers, which are unaware of the source of the font data.
+ These routines will be refered to as the bitmap font access
+ methods.

+ The function pointers are split out from the data structure to

+ Each new font path member is passed to this function; if
+ the return value is <errorname>Successful</errorname>, then
+ the FPE recognises the format of the string. This does not
+ guarantee that the FPE will be able to successfully use this

+ requested font server and prepares for using it. This

+ returns <errorname>FPEResetFailed</errorname> if (for some
+ reason) the reset failed, and the caller should remove the
+ old FPE and simply create a new one in its place. This is
+ used by the disk-based fonts routine as resetting the
