[doc] Issues in perlopenbsd.1perl

[hmartink]

Dear Perl maintainer,
the manpage-l10n project[1] maintains a large number of translations of
man pages both from a large variety of sources (including Perl) as
well for a large variety of target languages.

During their work translators notice different possible issues in the
original (english) man pages. Sometimes this is a straightforward
typo, sometimes a hard to read sentence, sometimes this is a
convention not held up and sometimes we simply do not understand the
original.

We use several distributions as sources and update regularly (at
least every 2 month). This means we are fairly recent (some
distributions like archlinux also update frequently) but might miss
your latest upstream version once in a while, so the error might be
already fixed. We apologize and ask you to close the issue immediately
if this should be the case, but given the huge volume of projects and
the very limited number of volunteers we are not able to double check
each and every issue.

Secondly we translators see the manpages in the neutral po format,
i.e. converted and harmonized, but not the original source (be it man,
groff, xml or other). So we cannot provide a true patch (where
possible), but only an approximation which you need to convert into
your source format.

Finally the issues I'm reporting have accumulated over time and are
not always discovered by me, so sometimes my description of the
problem my be a bit limited - do not hesitate to ask so we can clarify
them.

I'm now reporting the issues for your project. If future reports
should use another channel, please let me know.

Btw. I noticed that you said that missing perl-internal links are a
limitation of your toolchain, because in HTML it does not look right.
Is this still the case? Then I will not report this in the future,
but I think in HTML it is quite sensible, as this can then be turned
into proper hyperlinks within the Perl documentation, giving a nice
reading experience.

PS. I left of the triple backticks as requested, hopefully this
remains readible.

Man page: perlopenbsd.1perl
Issue 1: function → functions
Issue 2: Current Perl's → Current Perls

"When Perl is configured to use ithreads, it will use re-entrant library "
"calls in preference to non-re-entrant versions. There is an incompatibility "
"in OpenBSD\(Aqs CW<\(Cgetprotobyname_r\\*(C'> and " "CW<\\*(Cgetservbyname_r\(C'> function in versions 3.7 and later that will "
"cause a SEGV when called without doing a CW<\(C`bzero\(C'> on their "
"return structs prior to calling these functions. Current Perl\(Aqs should "
"handle this problem correctly. Older threaded Perls (5.8.6 or earlier) "
"will run into this problem. If you want to run a threaded Perl on OpenBSD "
"3.7 or higher, you will need to upgrade to at least Perl 5.8.7."
