That patch is too violent.  It could have many unintended consequences on other platforms.  The patch demands that all compilers return a non-zero exit code on a compilation error.

Yes, as I recall there were platforms with no errno.h.  However the new gz code doesn't need the errno.h check, so I will remove it.
