Try a newer GDB version.  I believe this is caused by a change in
headers in Cygwin very recently; you may need a current CVS snapshot in
order to fix it.

Huh?  I build Solaris-x-Linux and Cygwin-x-Linux debuggers fairly
frequently.  Cross debuggers take some care not to use target-specific
headers in the target-dependent files for exactly this reason.
