Hi!

clang's unhappy:

src/ModMap.c:86:15: error: passing 'KeyCode *' (aka 'unsigned char *') to parameter \
of type 'const char *' converts between pointers to integer types with different sign \
[-Werror,-Wpointer-sign]  Data(dpy, modifier_map->modifiermap, mapSize);
              ^~~~~~~~~~~~~~~~~~~~~~~~~
/archive/build/amd64.clang.20140330/usr/X11R7/include/X11/Xlibint.h:537:15: note: \
expanded from macro 'Data'  _XSend(dpy, data, len);\
                            ^
/archive/build/amd64.clang.20140330/usr/X11R7/include/X11/Xlibint.h:923:29: note: \
passing argument to parameter here  _Xconst char*       /* data */,
                                  ^
1 error generated.

Should I just cast it to (char *) or is there a better solution?
 Thomas
