(promotmatch) To remove this compilation error I replace these 3 lines static void error P((const char * message)); BY static void error P((const char* const string)); and static void error(string) const char* const string; BY static void error(const char* const string); Is there a compiler option to disable the prototype checking. Upgrade the zic.c source code file by replacing the prototypes a la Ansi-C is a nightmare, very long... Is there a compiler option to disable the compiler error to prevent me from updating the C source files until no compilation error appears. François REYGAGNE.
