To build GLib on Win32, you can use either gcc or the Microsoft
compiler and tools. Both the compiler from MSVC 5.0 and from MSVC 6.0
have been used successfully.
-But note that to just *use* GLib on Windows, there is not need to
-build it, prebuilt DLLs are available from the webiste above.

-With gcc I mean gcc-2.95 or gcc-2.95.2 as distributed by Mumit Khan,
-either as a mingw version (preferred), or running under cygwin. To
-successfully use gcc, follow the instructions below. We want to use
-gcc -mno-cygwin, i.e. produce executables (.exe and .dll files) that
-do *not* require the cygwin runtime library. This is called "mingw".
-I also use the -fnative-struct flag, which means that in order to use
-the prebuilt DLLs (especiall of GTK+), you *must* also use that flag.

bundled Microsoft C library (msvcrt.dll) and the pthreads-win32
library. For instance, pathnames are in the native Windows syntax.
-- _WIN32 is defined by the compiler
+- G_WITH_CYGWIN is defined if compiling for the Cygwin
+ environment. Note that G_OS_WIN32 is *not* defined in that case, as
+ Cygwin is supposed to behave like Unix. Building for Cygwin is not
+ supported. Some people have presumably done it, but no changes have
+ been submitted back.
-The Win32 port uses the combination with both of those on. As
+The Win32 port of GLib and related software uses only G_OS_WIN32. As
G_OS_WIN32 is defined in glibconfig.h, it is available to all source
files that use GLib (or GTk+, which uses GLib).
Additionally, there are the compiler-specific macros:
-- _MSC_VER is defined when using the Microsoft compiler
- __GNUC__ is defined when using GCC
-
-Some of the usage of these macros used to be a bit mixed up, and had
-to be straightened out when adding the gcc support. In particular, I
-used to check for _MSC_VER in some places where I really wanted to
-check for the Microsoft C library, and those checks has now been
-changed to G_OS_WIN32.
+- _MSC_VER is defined when using the Microsoft compiler
G_OS_WIN32 implies using the Microsoft C runtime MSVCRT.DLL. GLib or
software using it is not known to work with the older CRTDLL.DLL
Building software that use GLib or GTk+
=======================================
-Unfortunately, even building software that just *use* GLib or GTk+
-also require to have the right compiler set up the right way, so if
-you intend to use gcc, follow the relevant instructions below in that
-case, too.

Pthreads library
================
This is done automatically when an official GLib source distribution
package is built.
-Building with gcc

+Building GLib with gcc
+======================
I use the latest gcc, gcc-2.95.2. Version 2.95 will most probably also
work.
