Comments on xm-linux.h.  Just one problem (but it came from the other 
linux targets) and one question.

DJB,

I'm trying to build an s390 cross debugger.  Actually I'm trying to build:

	./configure --target=s390-elf

s390-elf being a a fairly generic s390 target.

The reason for doing this is to ensure that the non linix specific parts 
of the s390 target really are native independant.  If you check the
MAINTAINERS file you'll notice that all targets (with the exception of
the HP/PA, which has no maintainer) can be built as a cross debugger.

Any way, I'm not having much luck.

The configury changes needed for this are very straight forward.
Unfortunatly the tweeks to s390-tdep.c are not.  Sigh.  For the record, 
the problems are not new.

As I suggested last time, I can think of two possible courses of action:

	o	we try to fix the s390 problems
		and then get an IBM copyright transfer

	o	IBM transfer copyright for these files
		to the FSF and then they be included in
		GDB as a patch.  This would free up the
		code so that others can address the problems.

A very detailed commentry on the file s390-tdep.c is attached.
