And why does Perl's build think they are necessary, advertising them as required to build against Perl? Removing all those $(<lang>_CFLAGS) from the compile command for option.c fixes (or at least papers over the actual problem) on kfreebsd-amd64. It slightly helps on kfreebsd-i386, in that everything other than the Perl language bindings work. However, the language bindings themselves (which are tested during the build) crash with the useless backtraces seen before.
