   Mark, it would proably be useful to mention this in gdb/README under the 
   host/target section.

Which section do you mean?  We only have a section `Host/target
specific installation notes'.  Doesn't seem an appropriate section to
me.  Should I add a section `Known problems' for this purpose (just
before or after `Reporting Bugs')?

How about in NEWS?  We should tell there that SSE is supported (it wasn't 
in v5.0, right?), and while at that, mention the limitations.

If it wasn't in 5.0 then definitily a mention in news.

SSE was already mentioned.  Anyway, I checked in the attached patch.

If I changed the title to ``Host/target specific notes'' would it help?

I would like it to be possible for a user to just read (dare I say skim? 
:-) the README file and then successfully build GDB.  Having all the 
host/target specific issues in one spot would hopefully help this.

Yep, but ...

There is a considerable difference between Host/target specific
installation notes, Host/target specific runtime-problems.  The
installation notes are only relevant to the person that installs GDB,
while the "Known problems" are relevant to all users of GDB.  Perhaps
we can add a section to the GDB manual?

As Stan pointed out recently, we already have in the manual a chapter
named "Configuration-Specific Information".  All system-specific
information as well as target-specific commands should be documented
there, in appropriately-named sections.
