That's an old problem of having a standard that is never-changing.  When
the standard was made Windows was hardly a thing -- certainly not for
serious computing -- and they were concerned with portability to things
like Lisp machines that hardly even had an OS....

No, the problem is that the standard has never evolved beyond the
ANSI.... :-(  Seems like each of the implementations has some good
ideas, but none has all of the good ones.

I'll pull again and re-test.

It should make you feel better that your hard work on the regression
tests has let us spot these bugs almost instantly.
