As you might know, many of the libraries that fedora mingw project is
packaging were already ported and built since ages by Tor Lillqvist. It
is a great proceeding before one packages a library to visit
ftp://ftp.gnome.org/pub/GNOME/binaries/win32/ and check in the *-dev
packages the directory src/tml/make that contains Tor's build scripts
with inlined patches. This might be good to avoid having different ABI
versions of the same library out there in the wild.
