Interesting.  I wasn't aware that parallelism worked on Windows

Anyway, nowhere above have you declared that the "clean" target depends
on "build".  Also, you don't show the "build" target so all we can do is
assume it is not defined to depend on "clean".

That being the case, the order in which "build" is invoked relative to
"clean" is not defined.  It could be invoked first, or second.  I'm not
sure if this is your problem or not; without a definition of "build" I
don't see any other issue above.

You might check on the address@hidden mailing list for more help with
Windows-specific issues, as well.
