In that case, I agree.  Here's a patch to kludge the preference order
of termcap and curses for AIX 3.2.5.  It will replace my other one.
Please consider this one instead for inclusion.

Actually I don't think that's the best solution.  If sysadmins muck
with the system configuration and then install a new patch or update,
chances are the customizations will get overwritten.  What really
needs to be done is to fix the messed up terminfo stuff in an update
to AIX or whatever.  Then everyone can get this fixed.
