it looks like this is a real minGW not cygwin minGW. that may be the problem.
Make sure that you call the REAL location of gcc -- you have been
using the MinGW/official installed version (it doesnt work with
cygwin)
I'd look for gcc.exe myself in /usr/bin/ and /bin/ (among others) and
place that path into a var (maby "cygwin-gcc"?) so that calling
"$cygwin-gcc (files) to use the cygwin GCC... but im probobly
overcomplicating it.
