To build GLib on Win32, you can use either the Microsoft compiler and

Mumit Khan), running under cygwin-b20.1.
The egcs support was added quite recently, but seems to work in all
respects. Debugging with gdk works.

The egcs support was added quite recently, but seems to
work. Debugging with gdb works. I prefer to use the msvcrt runtime and
not the default crtdll. This can be achieved by applying the following
diff to the specs file, which typically is installed as
C:/cygnus/cygwin-b20/H-i586-cygwin32/lib/gcc-lib/i586-cygwin32/egcs-2.91.66/specs.
Sorry for the illegibility of this diff, but the specs file is like
that... This diff replaces -lcrtdll with -lmsvcrt, replaces crt1 with
crt2, and defines __MSVCRT__.

Note: If you build with gcc, you should also fix the definition of
_dev_t in the header mingw32/sys/types.h to correspond to what it
actually is used by msvcrt.dll. It should be unsigned int, not
short. Otherwise stat() calls will fail.
Before building you must get the pthreads library for Win32 from
http://sourceware.cygnus.com/pthreads-win32/. The pthreads-win32
snapshot from 1999-04-07 is the one that should be used. Edit the
location of the pthreads library and include files in

With a little work, it might be possible to use the ./configure
mechanism also with a "mingw32" configuration.
