Aha, this may be why Mads was seeing problems.  Although it should still
compile the module without the curses stuff as a fallback, so I'm
not convinced...

Is termcap still available?  I can't see it in the link line, which is
suspicious.  What did configure say when it was looking for tgetent
and tigetflag (from config.log)?

I thought it stored the configure variables somewhere?  I haven't seen this
problem for some reason.  I've got 2.50 here and something later at home.

Yes, I was thinking that.
