if this is the case, I must have missed it.

This is ok.

I wasn't thinking of gfortran.sum, it's about the total overhead of
the testsuite (dejagnu etc.).  But thanks for combining the tests!

Well, patches should always go the gcc-patches@, see e.g.

https://gcc.gnu.org/gitwrite.html

On the other hand, many *Fortran* reviewers will ignore patches
there and look at them only when they are sent to fortran@.

Thanks for your patch, pushed as r13-6338-gbcbeebc498126c .
