The latter part (the one about non-C89 comments or for loop declarations) should now be solved by 0.03. The former part, about perls older than 5.24 not supporting blk_oldsaveix, is a rather fundamental limit of the current code, which I haven't yet bothered trying to backport to older perls. I shall leave it as it is for now, and see how far I can backport to older versions once it actually works and is useful on 5.24+ -- Paul Evans

That part is now split out into a new bug - https://rt.cpan.org/Ticket/Display.html?id=122252 This one can now be closed. -- Paul Evans
