We use a cross-compiler from i686-linux to build the mingw compilers. 

I suspect your problems are occurring because your CFLAGS will be used when 
building programs for the build machine (ie. cygwin).

I'm not really familiar with the details of building on cygwin. Try 
configuring with --build=i686-migw32 or -build=i686-cygwin, see if that makes 
any difference.

If that fails, all I can suggest is either use a cygwin->mingw cross-compiler, 
or write a script that pretends to be a mingw cross compiler by invoking gcc 
-mno-cygwin.
