Setting up Mingw
A tutorial for how to set up a MINGW build environment.
Follow these instructions carefully 
Get these packages from here
Download Gnome binary packages from here. Under gtk+ there is a bundle that has several you need. These get installed in c:\MinGW\
and I'm currently stuck here. Running aclocal in the gnomesword directory appears to work, autoconf has an error
configure.in:48: error: possibly undefined macro: AC_PROG_INTLTOOL If this token and others are legitimate, please use m4_pattern_allow. See the Autoconf documentation.
and automake says
cannot open < gnome-doc-utils.make: No such file or directory
configure then gets confused on
line 2622: syntax error near unexpected token 'GNOME' 'PKG_CHECK_MODULES(GNOME, ' etc
so for some reason it isn't actually calling pkg-config
