Building dejagnu with latest GCC

[Richard Kenner]

    Does -fpermissive help?

I can't figure out how to add it except by modifying the Makefile, but when
I do, it *appears* to help, since it looks like it's changing errors
into warnings, but the command still fails.  I'm not sure why, though, since
the error message output is confusing:
