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/ .

The current (CVS) version of the Win32 backend is *not* as stable as it
was before the no-flicker branch was merged. A zipfile with that
version is available from http://www.gimp.org/win32/. That should be
use by "production" code until this CVS version is usable. (But note,
the Win32 backend has never been claimed to be "production quality".)

To build GTk+ on Win32, you need either the Microsoft compiler and
tools, or gcc-2.95 or later. The mingw setup of gcc is preferred, but
you can run gcc also under cygwin-b20.1 or later. Compile in
gdk\win32, gdk and gtk with `nmake -f makefile.msc` or `make -f
makefile.cygwin`. The name makefile.cygwin is misleading, it should
really be called makefile.mingw.

See the README.win32 file in the GLib distribution for instructions
how to build with gcc.

To use GTk+ on Win32, you also need either of the above mentioned
compilers. Other compilers might work, but don't count on it.  The
same instructions on how to set up a correct version of gcc should
also be followed if you want to build applications that use GTk+ 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 and remove references to
the wntab32x library from the makefile 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 as a DLL called gnu-intl.dll (the "gnu" prefix is used
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"
part of it which is 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.
