Actually, I see that's a standard feature of putenv supposedly. What
systems is it not? Would be nice to have a reminder of them.
Perhaps it's enough to just use unsetenv if it exists, and presume
when it doesn't that putenv is fully functional. Could start with
that until proven otherwise. (With an addition to the test-suite to
pick up any problem.)
/* No '=' in argument means we should remove the variable from
the environment. Not all putenvs understand this. To be
safe, we do it explicitely using unsetenv. */
#ifdef HAVE_UNSETENV
if (strchr (SCM_STRING_CHARS (str), '=') == NULL)
{
unsetenv (SCM_STRING_CHARS (str));
return;
}
#endif

Oh, not good. Would be worth having a comment to that effect. You
know how conditionals for strange environments build up until no-one
can remember why they were added :-).
