Huh?
I'm not talking about some kind of backwards-(in)compatibility
issue. I just tried to compile (with bleadperl) an XSUB that
used dUNDERBAR and ran into an error that the dynamic linker
couldn't resolve pad_findmy. That's because the symbol is
Perl_pad_findmy, and usually the macros in embed.h take care
of turning * into Perl_*. But right now we have:
#ifdef PERL_CORE
#define pad_findmy Perl_pad_findmy
#endif
Thus, the macro isn't visible to an XSUB...
