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.
