Well, I just noticed that after running the autoconf test suite under 
1.3.2 -- which passes -- I have a bunch of ac* directories left in my 
/tmp dir, as well.  (I didn't *specifically* notice before, because I 
thought those dirs were leftovers from failed automake or libtool tests, 
not autoconf).

Perhaps 1.3.2 is just "lucky" -- did the mechanism for assining PIDs (as 
seen by cygwin processes) change between 1.3.2 and 1.3.3; that is, are 
PIDs more likely to collide now?

Or, did the return val of mkdir() change when dir-already-exists?

Of course, even if I'm right about the PID issue (and I doubt it) the 
inability to remove dirs under 1.3.3 would still be a problem...
