And latest Ubuntu, which is why my g++ smokers have been paused.

Latest glibc added __THROW to the malloc-like function declarations which
expands to "throw ()" and the lack of it in Perl's malloc-like
declarations causes a conflict.

So we need to​:

#ifndef __THROW
#define __THROW
#endif

and add __THROW to the Perl malloc-like functions.

I've been meaning to commit such a fix for a while now but maybe finally
tonight.

Removing the PERL_MALLOC_OK => 1 in ext/SDBM_File/Makefile.PL also allows perl to build.

#defining those names (malloc, calloc, realloc, free) is fairly questionable from a C standard point of view, since we still include the headers.

Just to get things to work again, I commited a patch with Tony's

FWIW, today I was able to successfully build and test Perl blead (which is RC1) on Ubuntu 13.10 with gcc 4.8.1 *with a smaller set of configuration options* than the other contributors to this RT have done. I am attaching the Perl -V output as perlVg++.txt

Thank you very much.
