Yes, indeed.  Some testcases may need to be updated to
account for the new error message or one may needs to
use the old testcase to adjust the conditional to not
trigger for the older testcase.  Also, note that I've
found invalid Fortran in testcases as I've fixed a 
bug.

When parsing a file, gfortran runs a series of matchers.
If a failure is detected in a matcher an error message
is queued, and then other matchers are run.  If no matcher
succeeds in matching a statement, the last queued error
message(s) is(are) emitted and gfortran will exit.  If a
matcher does match a statement, then the error queue is
cleared and the next statement is parsed.  Sometimes a
new patch will find invalid Fortran in the testsuite.
