Recent versions of Devel::PPPort try to redefine eval_pv() to dodge a bug in pre-5.31 Perl versions. Unfortunately the redefinition fails on compilers that don't support statements nested within expressions. However, we aren't actually interested in this bug fix, since we always call eval_pv() with croak_on_error = FALSE. So, until there's an upstream fix for this breakage, just comment out the macro to revert to the older behavior. Per report from Wei Sun, as well as previous buildfarm failure on pademelon (which I'd unfortunately not looked at carefully enough to understand the cause). Back-patch to all supported versions, since we're using the same ppport.h in all.
