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 egcs-1.1.2 running under cygwin-b20.1. Before compiling, check the BIN definition in gdk\win32\makefile.msc (or makefile.cygwin) and gtk\makefile.msc (or makefile.cygwin). Compile in gdk\win32 and gtk with `nmake -f makefile.msc` or `make -f makefile.cygwin`. See the README.win32 file in the GLib distribution for preparations to build with egcs on cygwin. The tablet support uses the Wintab API. The Wintab development kit can be downloaded from http://www.pointing.com.
