OK, your /usr/include/err.h doesn't have the annotations to tell gcc that it
doesn't return.

Mine looks like so (Ubuntu):

	extern void err (int __status, __const char *__format, ...)
	     __attribute__ ((__noreturn__, __format__ (__printf__, 2, 3)));

I've CC'd the cygwin list: there might be a good reason why they don't
have annotations on their err.h, or it might just be an omission.

Thanks,
Rusty.
