There simply is no standard way to do it currently — putenv, unsetenv is posix only. No matter what I think this should be fixed.

Are we talking about (the combination of) fork + exec
(i.e. a new program image is being executed), or
about fork alone?

If the former, we do need the ability to define the
environment of the new process, but it seems wrong
on so many levels to change the environment of the
current process to make that happen.

For example, my Linux box has execvpe to pass
a fresh environment to the new process.
