Great! Did you try this with a dg-error testcase? I'm curious, because I did the
same AFAICT without diving into the code, but for some reason the regular
expression didn't catch our multi-line error messages -- even after I had
adapted our error printing routines to print file and line like g77 (i.e.
without the leading " In file") -- and therefore those tests failed with
"excess errors".

Thanks,
