FYI Perl 5.6.0 was released in March 2000. 5.6.2 in November 2003.
Gosh, I feel old. I started on Perl 4.036.
What is worth a little bit of effort to establish is exactly what
version of Perl we're already depending on, so that we can document
that for the benefit of future tool writers. There's no reason why
this particular thing needs to be compatible further back than
what is
already required otherwise.
I'd like to know the earliest version of perl that's supported for
PL/Perl, if that's ever been determined (I've not seen it in the
docs).
plperl requires Safe v2.09, released in Oct 2003 and included in
5.8.1.
That version, and later versions, have only been tested back to
perl 5.6.
I'd recommend Perl 5.6(.2) as a minimum for threads/multiplicity.
Perl 5.5 had complelely different, and unsafe, code for threads
and no concept of multiplicity.
I'd recommend Perl 5.8(.1) as a minimum for UTF-8 databases.
Perl 5.7 had a complelely different, and flawed, concept of
Unicode operation.
Tim.
p.s. I'll test PL/Perl with perl 5.6.2 (assuming I can still build
it on
my system) as part of testing the PL/Perl patches I'm working on.
It's possible that we might support building the release in general
with an older version of Perl than what we support for PL/perl, but
it
sounds like we may have already burned this bridge if the MSVC stuff
expects something newer. Maybe we should just document that 5.6 is
The MSVC stuff is only tested on 5.8.
the minimum supported version to build from source and be done with
it
(we should clarify what MSVC requires). If someone is running a

Yeah, very much like that. :-)
