bug fix to XLISP

[Jay C. Weber]

I got a bug fix to the previously posted XLISP sources from
ihuxt!paulson.  The source file concerned is xlisp.h, and here
is a diff of the fix:

% diff xlisp.old xlisp.c
6a7
> typedef int jmp_buf[10];
35c36
< static char ljmp[6];
---
> jmp_buf ljmp;

It seems that the previous jump buffer was not sufficient for some
systems, notably system 5 Unix.
