It sounds to me as if you're mixing C runtimes.  It is possible to use gcc
either cygwin or mingw32 to use the different runtime but it isn't going to be
a simple matter of just compiling and linking.  You'll have to ensure that the
proper headers for the runtime you're using are being used.  You may even have
to supply the startup code.  Beyond that you're into experimenting with the
frontiers of compiler/runtime technology.
