steve,

with your patch i get no change in the testsuite on i686/gnu/linux:

before:
		=== gfortran Summary ===

# of expected passes		4757
# of unexpected failures	1
# of unexpected successes	5
# of expected failures		21
/usr/work/2004344/ibin/gcc/testsuite/../gfortran  version 4.0.0 20041209 (experimental)


after:
                === gfortran Summary ===
 
# of expected passes            4757
# of unexpected failures        1
# of unexpected successes       5
# of expected failures          21
/home/work/gfortran/current/bin/gcc/testsuite/../gfortran  version 4.0.0 20041209 (experimental)


i am running it on freebsd now, but it takes a few hours.  real curious
as to what it fixes in those test failures, probably something new to be
discovered in chasing that down.
