RE: [HACKERS] Why is libcurses added to build by configure?

psql (at least in 6.3.2) uses curses and readline. I know this because I
tried to compile under a SuSE 5.3 distribution. Configure couldn't find the
curses library, so it wasn't added to LIBS, so the linker didn't try to use
it, so psql had unresolved references, all of which seems to indicate (even
without reading the sources) that *something* in there wants curses. I.e.,
it's not just configure.

Interestingly, failing to find curses did NOT stop configure, it went on to
make everything. "make all" didn't stop when psql failed to build either - it
went on to report all well at the end. Not until "make install" did the
failure become evident (though it was logged of course).
