I believe this is yet another instance of the problem that I have
described here:
http://sources.redhat.com/ml/cygwin/2004-08/msg01025.html

Seems like more than a few people are hitting this sore spot.

Further investigation of my original case indeed shows that consecutive
runs of configure need not result in the same output. The spaces I
threw into the mix are probably of no consequence.

When I try to slim down the configure script to produce a more
manageable test case, the bug apparently gets harder to trigger the
more I trim from the configure script.

Looks like a race to me.

Cheers,
Peter
