Ew, yoinks. That's definitely a bug -- looks like we used an
AM_CONDITIONAL inside the main configure.m4 for ptmalloc2; whoops (it
needs to be inside MCA_memory_ptmalloc2_POST_CONFIG, not
MCA_memory_ptmalloc2_CONFIG). You're building up quite the bug list
-- thanks for your patience! It's probably unfortunately not that
surprising, though, since we don't test on Cygwin at all... :-\

I do the build system stuff in OMPI, but this part is all George /
Windows guys... Perhaps this is a difference compiling between
"normal" windows and Cygwin...?
