Maybe, we've both misunderstood.  gcc-2.95.2-6 is using CRTDLL runtime
with -mno-cygwin.  gcc-2.95.2-7 was (it no longer exists) using MSVCRT
runtime with -mno-cygwin.  It was gcc-2.95.2-7 that was missing the
__MSVCRT__ define.

However, gcc-2.95.2-6 has a problem also.  The libmoldname is to be used
with MSVCRT and libcoldname is to be used with CRTDLL.  This was caused
by a change by me in the mingw-runtime package.  However, the _stati64
structure shouldn't work with CRTDLL so perhaps you even lucky at that.

HTH,
Earnie.
