So you can either run the program multiple times from within dejagnu, or
fork inside of the macros.  In any case, adding > 5MB of gtest just for that
single test or two is IMHO really too much, and similarly adding gtest
as another requirement to build gcc.  Does gtest support all the targets
that gcc does btw?
