Yeah, that makes sense.  This is a sort of generic problem in dejagnu.

Anyway, I am not sure this approach will work, because gdb_test calls
gdb_test_multiple, which has a different default and which also may call
'fail'.

One approach would be to refactor these procs so that your use can work.
I think this would be nice to have -- I think it would be good to have
fewer boilerplate tests with "synthetic" names, ones that nobody is
interested in.

Another approach would be to just give up and add a new test.  That is
sort of more traditional ;-)
