dnl Curses detection: Munged from Midnight Commander's configure.in
dnl
dnl What it does:
dnl =============
dnl
dnl - Determine which version of curses is installed on your system
dnl   and set the -I/-L/-l compiler entries and add a few preprocessor
dnl   symbols
dnl - Do an AC_SUBST on the CURSES_INCLUDEDIR and CURSES_LIBS so that
dnl   @CURSES_INCLUDEDIR@ and @CURSES_LIBS@ will be available in
dnl   Makefile.in's
dnl - Modify the following configure variables (these are the only
dnl   curses.m4 variables you can access from within configure.in)
dnl   CURSES_INCLUDEDIR - contains -I's and possibly -DRENAMED_CURSES if
dnl                       an ncurses.h that's been renamed to curses.h
dnl                       is found.
dnl   CURSES_LIBS       - sets -L and -l's appropriately
dnl   CFLAGS            - if --with-sco, add -D_SVID3
dnl   has_curses        - exports result of tests to rest of configure
dnl
dnl Usage:
dnl ======
dnl 1) Add lines indicated below to acconfig.h
dnl 2) call AC_CHECK_CURSES after AC_PROG_CC in your configure.in
dnl 3) Instead of #include <curses.h> you should use the following to
dnl    properly locate ncurses or curses header file
dnl
dnl    #if defined(USE_NCURSES) && !defined(RENAMED_NCURSES)
dnl    #include <ncurses.h>
dnl    #else
dnl    #include <curses.h>
dnl    #endif
dnl
dnl 4) Make sure to add @CURSES_INCLUDEDIR@ to your preprocessor flags
dnl 5) Make sure to add @CURSES_LIBS@ to your linker flags or LIBS
dnl
dnl Notes with automake:
dnl - call AM_CONDITIONAL(HAS_CURSES, test "$has_curses" = true) from
dnl   configure.in
dnl - your Makefile.am can look something like this
dnl   -----------------------------------------------
dnl   INCLUDES= blah blah blah $(CURSES_INCLUDEDIR)
dnl   if HAS_CURSES
dnl   CURSES_TARGETS=name_of_curses_prog
dnl   endif
dnl   bin_PROGRAMS = other_programs $(CURSES_TARGETS)
dnl   other_programs_SOURCES = blah blah blah
dnl   name_of_curses_prog_SOURCES = blah blah blah
dnl   other_programs_LDADD = blah
dnl   name_of_curses_prog_LDADD = blah $(CURSES_LIBS)
dnl   -----------------------------------------------
