* 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.
