Ahhhh, avoiding invalid syntax is key ;o)
Thanks, I'll have this in the clients tomorrow night!!

Hi Carter,

I think the following patch will correct the detection of initscr()
in -lcurses.

I moved the check for initscr() in -lcurses from the "else" part
of "AC_CHECK_LIB(ncurses, initscr..." to the "else" part of
"AC_CHECK_HEADER(ncurses.h...". This seems more logical to me: If the
the ncurses.h header file is there we want to check for initscr() by
linking against -lncurses. If ncurses.h doesn't exist we'd want to check
for initscr() by linking against -lcurses.

I believe you also have to quote the nested calls to AC_CHECK_LIB with
[brackets] or autoconf will generate invalid syntax.

 if test $CURSESLIB = "-lncurses"; then

ratop now compiles correctly for me.
