Something so fundamental would have been corrected long ago if folks were seeing
it in general.  I don't see it on my system, for instance.  It is far more
likely you've got BLODA.  See
<http://cygwin.com/faq/faq.using.html#faq.using.bloda> for details.

Note that you might have BLODA that's not on that list yet because nobody's
reported it as BLODA.  Also note that disabling the BLODA might not make any
difference; you have to remove it from your system to know for sure whether it
was the problem.  The above Web page gives the gory details why this is so.
HTH,
