new bug in gplt_x11.c

[Allin C. <cot...@wf...>]

Following recent changes, gplt_x11.c will not compile using gcc
4.4.3:

gplt_x11.c: In function 'preset':
gplt_x11.c:5025: error: incompatible types when assigning to type
'char[256]' from type 'void *'

The offending line is

  buffer = NULL;

'buffer' having been previously declared as of type char[256].

The bad line is reached if XAPPLRESDIR is defined neither in the
environment nor in the gnuplot source itself, I think.

I'd try for a patch but I don't quite understand the logic in that
part of the code.
