This is a bug report for perl from hv@crypt.org,
generated with the help of perlbug 1.39 running under perl 5.10.1.

-----------------------------------------------------------------
[Please describe your issue here]

The cellular automaton simulator 'golly' (http://golly.sourceforge.net/)
has embedded perl (and python) support from C++. Note that it requires
a perl built with threading support.

Building golly-src-2.1 with perl-5.8.8 gives me the warning:
  cc1plus: warning: command line option "-Wdeclaration-after-statement" is valid for C/ObjC but not for C++
.. but otherwise works fine.

Building with perl-5.10.0 works fine, with no warnings.

Building with perl-5.10.1 or with perl-5.11.2 fails with this error at link
time:

make: *** [golly] Error 1

The missing symbol is mentioned as a newly added function in the 5.10.1
and 5.11.0 deltalogs, is this simply a failure to export the new symbol
correctly?

The linkage to perl in the application is handled entirely in the file
wxperl.cpp, I'm not sure if it's doing anything in unusually strange
ways. As far as I can see Perl_newSV_type is pulled in solely for
newAV() calls in this case.

I don't know much about embedding, so I hope this is obvious to someone.
I haven't yet contacted the golly maintainers, since to me this looks like
the problem is at perl's end.
