Experimentation with modern MinGW (specifically the 5.0.2 version packaged for Fedora 26) shows that its version of sys/stat.h *does* provide S_IRGRP and friends, contrary to the expectation of win32_port.h. This results in an astonishing number of compiler warnings, and perhaps in incorrect code --- I'm not sure if the nonzero values supplied by MinGW's header actually do anything. Hence, adjust win32_port.h to only define these macros if <sys/stat.h> doesn't. This might be worth back-patching, but given the lack of complaints so far, I'm not too excited about it.
