You're welcome. It was fun.

The only real patching was for geos. The adjusted patch has already been 
accepted upstream, so I've noted it here:

http://hg.savannah.gnu.org/hgweb/mingw-cross-env/rev/8799139fb839

The other issues that came up:

1. Addition of -Wno-unused-but-set-variable
This was needed for compiling our test programs for guile, jpeg, sdl, 
sdl_mixer.
Otherwise needed for:
guile
physfs

2. Removal of apparently obsolete gcc flag -mno-cygwin
Used sed to strip from configure script.
Needed for:
fltk
libdnet
winpcap
xvidcore

3. Removal of apparently obsolete gcc flag -no-undefined
Used sed to strip from configure script.
Needed for:
exiv2
xine-lib

I'm not sure it's worth the trouble to contact the upstream projects 
about 1,2 and 3. What do you think?

regards,

Mark
