That seems pretty invasive; I'm not excited about breaking a lot of
unrelated code (particularly third-party extensions) for plperl's benefit.
Even if we wanted to do that in HEAD, it seems like a nonstarter for
released branches.
An even bigger issue is that if Perl feels free to redefine sigsetjmp,
what other libc calls might they decide to horn in on?
So I was trying to figure a way to not include XSUB.h except in a very
limited part of plperl, like ideally just the .xs files. It's looking
like that would take nontrivial refactoring though :-(. Another problem
is that this critical bit of the library API is in XSUB.h:
#if defined(PERL_IMPLICIT_CONTEXT) && !defined(PERL_NO_GET_CONTEXT) &&
!defined(PERL_CORE)
# undef aTHX
# undef aTHX_
# define aTHX PERL_GET_THX
# define aTHX_ aTHX,
#endif
As best I can tell, that's absolute brain death on the part of the Perl
crew; it means you can't write working calling code at all without
including XSUB.h, or at least copying-and-pasting this bit out of it.
