including <stdlib.h>

There are everal things that are crying out for global headers - for
example our protos for error().   Certainly, this approach would also
help contain ugliness like we talked about recently with the collisions
of <string.h> & <strings.h>.

I don't see a really obvious candidate in gcc/*config.h.   Can you be
more specific in your recommendation?   Is there an existing file you're
thinking of?
