No, it does not since the perl program checked by Configure is still 
used at build-time. My patch only changes things at run-time, not 
build-time.

True, but that's not applicable for my patch (the scripts I am changing 
do not have flags). In any case, -w can be changed to "use warnings" if 
needed.

...which is true in practice. I think it's a lot safer to assume the 
existence of /usr/bin/env than to assume that two different systems will 
have the same path to Perl (especially since the default perl found in 
$PATH could be in some non-standard location).
