Configure problem

[Mark Loftis <mark@xanadu.paradize.net>]

I had some trouble using the new configure script on a
Slackware 3.1 system. It failed to detect my ncurses lib
and added some extra externs for strstr and getcwd. A little
digging discovered the conftest programs failed from
a bad command line, not missing libraries. They were linking
to X with only some of the needed flags. Here's a patch
to fix the ncurses and strstr sections. There may be others
like this, but these were the only two I needed to get it to work.
