Nasty.  Even more, the current code assumes
that alignof (arg.watch) == alignof (prwatch_t)).

Did you consider fixing this, and posting a patch at gdb-patches@ ?

[...]

If you look at the log file, does it look like many failures are
related to \r\n patterns being misdetected?  Passing --debug to RUNTESTFLAGS
will make it easier to spot.  I had some troubles related to that when
I last ran the testsuite on that version of Solaris.  See here:

  http://sourceware.org/ml/gdb/2008-08/msg00144.html

I still don't know what the proper fix is.

Someone has to put effort into making that happen.
