Oh, I guess the point is that WIN32_ONLY_COMPILER doesn't get defined,
and that block of file-permission-bit #defines is nested inside
#ifdef WIN32_ONLY_COMPILER.

So apparently the issue is that the mingw headers provide some but not
all of those symbols.  Which have they got, and how are they defined?
