Have put a copy of libtermcap.a in the appropriate directory in the source
tree and re-linked the code. The version came from the usr/lib directory of
the cygwin installation. This still does not work so maybe this is still a
shared library. Any ideas where I can get the source code for the libtermcap
sub-directory to try that.
