Tor uses gcc with the -mms-bitfields flag which means that in order to
use the prebuilt DLLs (especially of GTK+), if you compile your code
with gcc, you *must* also use that flag. This flag means that the
struct layout rules are identical to those used by MSVC. This is
essential if the same DLLs are to be usable both from gcc- and
-MSVC(6)-compiled code. Such compatibility is desirable.

When using the prebuilt GLib DLLs that use msvcrt.dll from code that
uses other C runtimes like for example msvcr70.dll, one should note
-that one cannot use such GLib API that takes or returns file

descriptors. On Windows, a file descriptor (the small integer as
returned by open() and handled by related functions, and included in
the FILE struct) is an index into a table local to the C runtime

-Before building GLib you must also have the libiconv library and GNU
-gettext. Get prebuilt binaries of libiconv (1.9.1 or newer), and
-gettext-runtime (0.13.1 or newer) from www.gimp.org/win32/downloads.html.

Autoconfiscated build (with gcc)
================================
-Tor uses gcc 3.4.5 from www.mingw.org, and the rest of the mingw
-utilities, including MSYS. Somewhat earlier or later versions of gcc
-presumably also work fine. Using Cygwin's gcc with the -mno-cygwin
-switch is not recommended. In theory it should work to use the
--no-cygwin flag, but Tor hasn't tested that lately, and it can easily
-lead to confusion where one mixes up headers for Cygwin from
-/usr/include with the headers one really should use. Ditto for
-libraries.

Please note that the ./configure mechanism should not blindly be used
to build a GLib to be distributed to other developers because it
-produces a compiler-dependent glibconfig.h. (Also config.h, but that
-shouldn't matter, as it isn't seen by GLib-using applications). For

-Except for this and a few other minor issues, there really shouldn't
-be any reason to distribute separate GLib headers and DLLs for gcc and
-MSVC6 users, as the compilers generate code that uses the same C
-runtime library. The DLL generated by either compiler is binary
-compatible with the other one. Thus one either has to manually edit
-glibconfig.h afterwards, or use the supplied glibconfig.h.win32 which
-has been produced by running configure twice, once using gcc and once
-using MSVC, and merging the resulting files with diff -D.
