bug fix to XLISP

[Jay C. Weber]

Russ <Smith at nrl-aic> has pointed out a bug in XLISP that others
may be running across.  It seems that the XLISP code, "xldmem.c"
in particular, counts on statics being initialized to NULL.
Although that may be a problem in other parts, he has pointed
out two places where it is can be fatal (Segmentation fault):

$ diff xldmem.c xldmem.old
49,50c49,50
< static struct segment *segs = NULL;
< static struct node *fnodes = NULL;
---
> static struct segment *segs;
> static struct node *fnodes;


If others find bugs, I would be glad to hear about them and then
post a bug fix.  I asked before not to address questions to me
because I knew little about the internals of the program; I wouldn't
mind being in charge of bug fixes you report.
