ncursesw-morphos/Ada95/aclocal.m4
Thomas E. Dickey bdb754b9f0 ncurses 6.0 - patch 20160903 
+ correct 20100515 change for weak signals versus sigprocmask (report
  by Rich Coe).
+ modify misc/Makefile.in to work around OpenBSD "make" which unlike
  all other versions of "make" does not recognize continuation lines
  of comments.
+ amend the last change to CF_C_ENV_FLAGS to move only the
  preprocessor, optimization and warning flags to CPPFLAGS and CFLAGS,
  leaving the residue in CC.  That happens to work for gcc's various
  "model" options, but may require tuning for other compilers (report
  by Sven Joachim).

dnl -------------------
dnl Look for the SVr4 curses clone 'ncurses' in the standard places, adjusting
dnl the CPPFLAGS variable so we can include its header.
dnl
dnl The header files may be installed as either curses.h, or ncurses.h (would
dnl be obsolete, except that some packagers prefer this name to distinguish it
dnl from a "native" curses implementation). If not installed for overwrite,
dnl the curses.h file would be in an ncurses subdirectory (e.g.,
dnl /usr/include/ncurses), but someone may have installed overwriting the
dnl vendor's curses. Only very old versions (pre-1.9.2d, the first autoconf'd
dnl version) of ncurses don't define either __NCURSES_H or NCURSES_VERSION in
dnl the header.
dnl
dnl If the installer has set $CFLAGS or $CPPFLAGS so that the ncurses header
dnl is already in the include-path, don't even bother with this, since we cannot
dnl easily determine which file it is. In this case, it has to be <curses.h>.
dnl
dnl The optional parameter gives the root name of the library, in case it is
dnl not installed as the default curses library. That is how the
dnl wide-character version of ncurses is installed.

dnl --------------
dnl --------------
dnl Attempt to determine the appropriate CC/LD options for creating a shared
dnl library.
dnl
dnl Notes:
dnl a) ${LOCAL_LDFLAGS} is used to link executables that will run within
dnl the build-tree, i.e., by making use of the libraries that are compiled in
dnl $rel_builddir/lib We avoid compiling-in a $rel_builddir/lib path for the
dnl shared library since that can lead to unexpected results at runtime.
dnl b) ${LOCAL_LDFLAGS2} has the same intention but assumes that the shared
dnl libraries are compiled in ../../lib
dnl
dnl The variable 'cf_cv_do_symlinks' is used to control whether we configure
dnl to install symbolic links to the rel/abi versions of shared libraries.
dnl
dnl The variable 'cf_cv_shlib_version' controls whether we use the rel or abi
dnl version when making symbolic links.
dnl
dnl The variable 'cf_cv_shlib_version_infix' controls whether shared library
dnl version numbers are infix (ex: libncurses.<ver>.dylib) or postfix
dnl (ex: libncurses.so.<ver>).
dnl
dnl Some loaders leave 'so_locations' lying around. It's nice to clean up.
