dnl CF_CONST_X_STRING version: 8 updated: 2023/12/01 17:22:50
dnl -----------------
dnl The X11R4-X11R6 Xt specification uses an ambiguous String type for most
dnl character-strings.
dnl
dnl It is ambiguous because the specification accommodated the pre-ANSI
dnl compilers bundled by more than one vendor in lieu of providing a standard C
dnl compiler other than by costly add-ons. Because of this, the specification
dnl did not take into account the use of const for telling the compiler that
dnl string literals would be in readonly memory.
dnl
dnl As a workaround, one could (starting with X11R5) define XTSTRINGDEFINES, to
dnl let the compiler decide how to represent Xt's strings which were #define'd.
dnl That does not solve the problem of using the block of Xt's strings which
dnl are compiled into the library (and is less efficient than one might want).
dnl
dnl Xt specification 7 introduces the _CONST_X_STRING symbol which is used both
dnl when compiling the library and compiling using the library, to tell the
dnl compiler that String is const.

dnl
dnl + It was adopted in NetBSD make in June 1995.

dnl that reason are not actually different "implementations").
dnl
dnl + Some features of NetBSD make were actually adapted from pmake, which

dnl
dnl + Version 3.8 of the dmake program in January 1992 also implemented this

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 CF_XOPEN_SOURCE version: 67 updated: 2023/09/06 18:55:27
dnl ---------------
dnl Try to get _XOPEN_SOURCE defined properly that we can use POSIX functions,
dnl or adapt to the vendor's definitions to get equivalent functionality,
dnl without losing the common non-POSIX features.
dnl
dnl Parameters:
dnl $1 is the nominal value for _XOPEN_SOURCE
dnl $2 is the nominal value for _POSIX_C_SOURCE
dnl
dnl The default case prefers _XOPEN_SOURCE over _POSIX_C_SOURCE if the
dnl implementation predefines it, because X/Open and most implementations agree
dnl that the latter is a legacy or "aligned" value.
dnl
dnl Because _XOPEN_SOURCE is preferred, if defining _POSIX_C_SOURCE turns
dnl that off, then refrain from setting _POSIX_C_SOURCE explicitly.
