That line of thought nudges us toward the place Linus explicitly
said he didn't want to see us going, no?  We do not particularly
want to care the exact nature of the breakage on MinGW.  Do we
really want to set a booby-trap that intimately knows about how
their strcasecmp is broken, and possibly cover breakages of the same
kind but with other functions?

It isn't like "we are deliberately relying on this non-standard
behaviour we see on the system _we_ commonly use, and somebody on
a new strictly POSIX platform may be bitten by it", in which case it
would make sense to have a test that intimately knows about the
non-standard behaviour we rely on.  This case is a total opposite.
