Here's another draft of the perl5/solaris/gcc sanity-checker. This is
reorganized and maybe simplified. I now use Andy's suggestion to use more
of the "gcc -v" output, so I'm asking gcc what it's doing and who it's
talking to rather than making my own guesses about these things. Also
removed the assumption that the gcc binary is called "gcc" (my sight
installed 2.7.0 as "gcc.270").
How about another round of comments?
