Because you are on Cygwin you should start with one of those mailing
lists.  Generally the Cygwin folks do good work but because of the
platform differences they often need to make deep invasive changes to
GNU/Unix software in order to make it run.  We understand that.
Sometimes compromises must be made.  I find it rather amazing that it
runs there at all!  Also people working on GNU Project software
usually don't run it on MS-Windows systems and don't unusually have
the ability to recreate problems on Cygwin.  Therefore the place to
start when using Cygwin is over on the Cygwin project side of things.

But wait...  I am a little confused.  Part of your configuration
appears to be Cygwin but other parts appear to be MinGW.  Are you
mixing those two projects together?  Perhaps that is the problem.  I
didn't think that mixing those environments was valid due to the
different choices made by those two projects to port code to
MS-Windows.  But since I am using neither I really don't know.

The MinGW mailing lists.

Good luck!
