CYGWIN != LINUX!!!! Oh, wait, this isn't cygwin-talk. Sorry...

There appears to be a conflicting contraints between mingw and 
gcc-mingw. The float.h provided by mingw definitely assumes that it will 
be included before the compiler provided float.h.

I am able to compile my app successfully by hardcoding the #include 
directive so that it picks up the mingw version of float.h first.

There may be some problems with some other files, but I do not know,

barney-xp$ /bin/ls /usr/lib/gcc-lib/i686-pc-mingw32/3.3.3/include > gcc.lst
barney-xp$ /bin/ls /usr/include/mingw > mingw.lst
barney-xp$ comm -12 gcc.lst mingw.lst
float.h
limits.h
stdarg.h
stddef.h
varargs.h
