Hm. I saw something similar on my old dinosaur pademelon, but wrote it
off as "they don't care about pre-C99 compilers anymore". But now I
dug into ppport.h a bit more, and I think it's actually busted for
non-gcc compilers: eval_pv expands into something that tries to use
STMT_START/STMT_END inside a plain parenthesized expression (via
croak_sv).
Maybe the bleeding edge Devel::PPPort would do better? I see
Revision history for Devel-PPPort
3.64 - 2022-02-01
* Fix: better support for STMT_START / STMT_END definition
* Fix: Only use '-Wdeclaration-after-statement' if possible
which if not a smoking gun is at least firearm-adjacent.
