Hi hackers,

Andres' recent post¹ about PL/Perl on Windows and linked-to² patch
containing an erroneous version check made me realise that we haven't
updated our copy of ppport.h since 2009.  Attached is a patch that does
that, and applies code changes suggested by running it.  I've tested
`make check-world` with `--with-perl` on both the oldest (5.8.9) and
newest (5.34.0) perls I have handy.

I also noticed that PL/Perl itself (via plc_perlboot.pl) requires Perl
5.8.1, but configure only checks for 5.8 (i.e. 5.8.0).  The second patch
updates the latter to match.
