The gcc equivalent of this would be

	int nProcesses __attribute__((section(".GLOBALS")) = 0;
	int nThreads __attribute__((section(".GLOBALS")) = 0;

However, I have no idea whether this works.

I do know that the technique of using

	#define nProcesses (*__imp_nProcesses)

works.  (This technique is automated if you use my Makefile.DLLs,
