608 dnl CF_CONST_X_STRING version: 4 updated: 2020/03/10 18:53:47
609 dnl -----------------
610 dnl The X11R4-X11R6 Xt specification uses an ambiguous String type for most
611 dnl character-strings.
613 dnl It is ambiguous because the specification accommodated the pre-ANSI
614 dnl compilers bundled by more than one vendor in lieu of providing a standard C
615 dnl compiler other than by costly add-ons. Because of this, the specification
616 dnl did not take into account the use of const for telling the compiler that
617 dnl string literals would be in readonly memory.
619 dnl As a workaround, one could (starting with X11R5) define XTSTRINGDEFINES, to
620 dnl let the compiler decide how to represent Xt's strings which were #define'd.
621 dnl That does not solve the problem of using the block of Xt's strings which
622 dnl are compiled into the library (and is less efficient than one might want).
624 dnl Xt specification 7 introduces the _CONST_X_STRING symbol which is used both
625 dnl when compiling the library and compiling using the library, to tell the
626 dnl compiler that String is const.

2525 dnl Look for the SVr4 curses clone 'ncurses' in the standard places, adjusting
2526 dnl the CPPFLAGS variable so we can include its header.
2528 dnl The header files may be installed as either curses.h, or ncurses.h (would
2529 dnl be obsolete, except that some packagers prefer this name to distinguish it
2530 dnl from a "native" curses implementation). If not installed for overwrite,
2531 dnl the curses.h file would be in an ncurses subdirectory (e.g.,
2532 dnl /usr/include/ncurses), but someone may have installed overwriting the
2533 dnl vendor's curses. Only very old versions (pre-1.9.2d, the first autoconf'd
2534 dnl version) of ncurses don't define either __NCURSES_H or NCURSES_VERSION in
2537 dnl If the installer has set $CFLAGS or $CPPFLAGS so that the ncurses header
2538 dnl is already in the include-path, don't even bother with this, since we cannot
2539 dnl easily determine which file it is. In this case, it has to be <curses.h>.
2541 dnl The optional parameter gives the root name of the library, in case it is
2542 dnl not installed as the default curses library. That is how the
2543 dnl wide-character version of ncurses is installed.
