You have multiple problems here.

It looks like something has changed which causes gdb to require the
sigtramp_saved_pc function.  I wonder if this is somehow due to Mark
Kettenis's changes of 2000-03-04.

Your other problems are due to the fact that you are mixing an old
library (libtermcap.a) with a newer libcygwin.a --  _ctype_ is no longer
defined in libcygwin.a.  The simple solution is to recompile libtermcap.a
using the headers and libraries in one of the cygwin snapshots.
