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

2558 dnl is already in the include-path, don't even bother with this, since we cannot
