Didn't work out for me.
FWIW, i tried
! { dg-do compile }
! { dg-options " -Werror" }
! { dg-final { scan-assembler ".*" { xfail *-*-*-* } } }
! PR fortran 21061

So i'll let dejagnu alone and simply omit the testcases.
I already wasted far too much time (and procrastinated the checkin!) for
this really simple glitch, given that the first incarnation i sent to
this list dates back to Sat, 26 Nov 2005 17:46:20 +0100.

I'll commit to trunk (and 4.2, 4.1 if i get a change to regtest them on
these) unless somebody raises objections within 24 hours from now on.

Thanks,
