mingw-targeted cross-compiler question

Thanks for explanation.  I checked the Make file, and here it is:

CFLAGS = -O3 -Wimplicit
...
gcc -mno-cygwin -g -Wl,--add-stdcall-alias -Wl,--export-all-symbols
${BRILL_INCLUDES} -I ${JAVA_HOME}/include/ -I ${JAVA_HOME}/include/win32
-shared -o lib/BTagger.dll ${BRILL_JAVA_BASE}/*.c ${BRILL_SRC}

This is a Java wrapper around a C/C++ library. Can you help have a look and
see if there is an easy change to the "gcc -mno-cygwin ..." part? I am using
Windows 7 64-bit machine.
Thanks.
