[joe] gcc-3.0.2 miscompiles joe-2.9.7

Hi,

I compiled joe-2.9.7 on a x86-linux system with the following CFLAGS:
-O2 -march=pentiumpro -mcpu=pentiumpro -mpreferred-stack-boundary=2 -s \
-fomit-frame-pointer

Starting joe results in

Processing '/etc/joerc'...Segmentation fault

(/etc/joerc exists). During compilation I got several warnings, most of 
them like
this ... e.g.

gcc -DHAVE_CONFIG_H -I. -I. -I. -DJOERC="\"/etc/\""    -O2 
-march=pentiumpro \
-mcpu=pentiumpro -mpreferred-stack-boundary=2 -s -fomit-frame-pointer \
-c `test -f rc.c || echo './'`rc.c

rc.c: In function `doopt1':
rc.c:393: warning: passing arg 1 of `msgnw' from incompatible pointer type
[... etc]

So I looked for the reason and found that the types 'struct window' (defined
in w.h) and 'struct bw' (defined in bw.h) seem to be incompatible with each
other. And if you read the definitions of these, it is obvious.
Astonishingly joe runs when I omit flags "-s -fomit-frame-pointer" and add
debug flag "-g" but I think this is related to the different behaviour 
of the stack.
In brief: it runs by accident!
