Yup.

Yes. I even documented all this some time back on
http://www.cygwin.com/ml/cygwin-apps/2001-11/msg00634.html, but
predicatably enough, no patches where forthcoming. Probably due to the
complete lack of a prebuilt bz2lib for mingw (that my cursory searches
have looked for).

Yes, please, please, yes. I would really really love it if some of the
common libs (zlib, bz2lib, stdc++) where available in a setup.exe
installable pacakge.

Yes. It gets rid of the need for mingw_foo in the make files, and makes
it explicit that we are cross compiling.

for cross compiles:
../setup/configure --host=i686-pc-mingw32 --build-i686-pc-linux
should do it (assuming a mingw32 cross compiler is present), or a
combination using the CC string you have above with the mingw host will
work too.

Ok, will do.

It really depends on what you want to do. Some stuff it does
spectalularly well, some things it has trouble with. With the 'cross
compiling but not' approach, it would almost certainly have some trouble
:}.
