This my patch
	http://sources.redhat.com/ml/gdb-patches/2007-12/msg00137.html

was more a demonstration that while running the testsuite as 'root' may be
wrong it happens and it probably should not be disabled.


This is repeating the history, warnings are not enough:
	http://sources.redhat.com/ml/gdb-patches/2007-01/threads.html#00326

There are various warnings around, at least I see now on the console
	WARNING: Couldn't find the global config file.

but apparently nobody cares (do you also see this warning?).  I had to start
resolving the testsuite regression to find out the reason is the 'root' run.
I am sure I would ignore another warning message appearing during the start.

There are multiple possibilities:

(1) Keeping there setuid() before somebody complains it does not work.
    http://sources.redhat.com/ml/gdb-patches/2007-12/msg00135.html

(2) Pointing me/anyone at the system where this setuid() code does not work.

(3) Skipping (not FAILing) the two tests known they FAIL on the 'root' run.

(4) Disabling running the testsuite as 'root'.

(5) Giving just a warning during the start.

(6) I am too dumb to become a GDB user.

more?

(4) and (5) are hopefully out of the question now.

Jan
