It is such a pain to build gcc. I think it used up an entire day when I built gcc 4.9.
That is an experience I hope never to repeat. Plus the cross compiler I downloaded
works just fine, so there isn't really a need.

Your saying there are computers out there without bash? It sounds hard to
believe. Bash is such a popular shell. Even Cygwin comes with bash. If 
bash is such a problem, then I guess I could use awk or something else
to do the work I need. I'm not honestly concerned with the theoretical. Is there
a unix-like system out there that doesn't come with bash that OpenBIOS is
expected to support?
