* configure.in (PERL, INSTALL_INFO): Don't AC_SUBST these,
since AC_PATH_PROG already does it for us.
(PERL): Rewrite check added in 2000-02-29 change for syntactic
correctness and sh portability. I replaced the broken check
with a more sensible implementation of the apparently intended
semantics, which might still be questionable. Using expr causes
a non-numeric value for `perl -V:apiversion` to be accepted,
refusing to use only a perl that reports a number less than 5;
on my system, perl (5.004_04) -V:apiversion produces UNKNOWN.
* configure: Regenerated.
