640 dnl -----------------
641 dnl The X11R4-X11R6 Xt specification uses an ambiguous String type for most
642 dnl character-strings.
644 dnl It is ambiguous because the specification accommodated the pre-ANSI
645 dnl compilers bundled by more than one vendor in lieu of providing a standard C
646 dnl compiler other than by costly add-ons. Because of this, the specification
647 dnl did not take into account the use of const for telling the compiler that
648 dnl string literals would be in readonly memory.
650 dnl As a workaround, one could (starting with X11R5) define XTSTRINGDEFINES, to
651 dnl let the compiler decide how to represent Xt's strings which were #define'd.
652 dnl That does not solve the problem of using the block of Xt's strings which
653 dnl are compiled into the library (and is less efficient than one might want).
655 dnl Xt specification 7 introduces the _CONST_X_STRING symbol which is used both
656 dnl when compiling the library and compiling using the library, to tell the
657 dnl compiler that String is const.

2582 dnl is already in the include-path, don't even bother with this, since we cannot
