I'm no cygwin developer, but:
It might be worth spending a little quality time with;a=tree;f=winsup/testsuite/winsup.api/ltp
to update it to handle the case you're interested in first...? has come a long, long ways
since cygwin's copy was made.  It might be interesting to just
try building and running LTP on cygwin and see how far it is from
working at all... I would not be surprised if cygwin's copy is highly customized
to avoid spikes.
