Headsup: HEAD of dejagnu (correctly) less warnings, marks unresolved test-cases

[Hans-Peter Nilsson]

In my gcc autotester, I check cris-elf using cris-sim (all
sources are in gcc and src trees) on a Fedora 8 amd64.

I'm also using amd64 Debian machines in the gcc build farm, but
not for autotesting.  That setup doesn't reveal that many
differences (more later), because I mentioned, Debian tracks
dejagnu closer.

This isn't IMHO a real a difference in test-results, but maybe
it's cause for questions (excerpt of diff between log files):

version 4.3.0 20080212 (experimental) [trunk revision 132266] (GCC) 

The "excess errors" are ld error undefined-reference messages
due to missing functions.  (The test should probably be skipped
as unsupported.)

The gfortran.dg/chmod_1.f90 testcase is marked:

! { dg-do run }
! { dg-options "-std=gnu" }

so I think the difference is an improvement: the "run" part is
now properly marked as "unresolved" and doesn't cause spurious
warnings when the test-case doesn't link.  All good.
