What environment is that?

Yes.  Gawk already supports a couple of environments like that.

Not much.  If your environment supports running the configure script,
perhaps none at all, as the configure script will take care of
everything for you.

Gawk uses fork for some obscure features like &| pipes.  Without fork,
these will simply be unsupported.
