The Win32 port of GTk+ is a work in progress, and not as stable or correct as the Unix/X11 version. For more information about the Win32 port, see http://www.gimp.org/tml/gimp/win32/ or http://www.iki.fi/tml/gimp/win32/ . To build GTk+ on Win32, you need either Microsoft compiler and tools, or gcc-2.95 or later running under cygwin-b20.1. Compile in gdk\win32 and gtk with `nmake -f makefile.msc` or `make -f makefile.cygwin`. Before doing a install, check the BIN definition in gdk\win32\makefile.msc (or makefile.cygwin) and gtk\makefile.msc (or makefile.cygwin). See the README.win32 file in the GLib distribution for instructions how to build with gcc. The tablet support uses the Wintab API. The Wintab development kit can be downloaded from http://www.pointing.com. If you don't care for that, undefine HAVE_WINTAB in config.h.win32 before building. GTk+ wants to be built with the GNU "intl" library for internationalisation (i18n). Get the version ported to Win32 (not a very big deal) from tml's web site mentioned above. We build the "intl" library to a DLL called gnu-intl.dll to reduce name clash risks. If you don't want any i18n stuff, undefine ENABLE_NLS, HAVE_GETTEXT and HAVE_LIBINTL in the config.h.win32 file, and remove references to the gnu-intl library from the makefiles. Note that while the GNU gettext package is under the GPL, the "intl" library part as distributed with GNU libc is under the LGPL (like GTk+ or GLib). We want the LGPL one, even if they are the same, more or less.
