I don't see anywhere that "-DPIC" is ever invoked on cygwin.  Please 
send a patch to libtool.m4 that fixes the problem for you.

BTW, somebody mentioned libtool CVS branch-2.0 as being too "cutting 
edge" for cygwin use...FYI, libtool-cvs-branch2.0 passes ALL regression 
tests which is better than libtool has EVER done on our platform.  I'm 
thinking of releasing a test version of the next beta...
