Re: New gdb 31 & 64 bit patches for S/390

["Denis Joseph Barrow" <DJBARROW at de dot ibm dot com>]

Hi Andrew,
I basically took this stuff from other architectures on gdb-5.0, I presume
they knew what they were doing &
something subtle would break if I didn't do it, I'm using the same source
base for the latest stuff & gdb-5.0
as much as possible to avoid maintaining 2 different incomatible source
bases.
So some definitions specific to gdb-5.0 ( which isn't multiarch capible )
will stay in /config/s390 header files
until gdb-5.1 or whatever is officially released.

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

FYI, This belongs in nm-linux.h (if it is needed at all).  The other

Something that should some day be moved to autoconf.

Is this needed?
