I will add.

Any clue if WinCE has this?

We can punt at least until compatibility becomes more of an issue.

Trunk's apr.hw can default it to enable, right?

The work you're consolidating/tweaking/??? has some bearing on this
general issue, right?  I also see some hints that MinGW relies on the
real MSVCRT (which one? urban legend?) but haven't delved into that at

If it becomes a concern, it will only be after more people start using
a reasonably working apr+httpd+??? and start flushing out corner
cases.  (But I speculate that the more surprising change will be more
patches for base Windows issues.)

I'll see what else I can tweak.
