Compiler warnings unnecessarily caused by X11 headers

it may be useful to compile programs with
gcc -Wall -Wwrite-strings -Wcast-qual
but unfortunately doing this causes numerous compiler warnings when defining
X11 resources. Attached is a small example resulting in 13 warnings
8 initialization discards qualifiers...
5 cast discards qualifiers...
All this is due to struct members declared as 'char *' or (char *) casts,
that actually should be 'const char *' or maybe '_Xconst char *'.
I'd think that it is about time to make these changes (knowing well that
they will imply corresponding changes in many other declarations).
Doing this right will, however, also be a good check that these string are
not modified by the X11 library code.
