The problem occurs under 5.10.0. My module was developed under 5.8.9. (I'll update my problem statement with this fact also.)

Devel::PPPort says it "attempts to bring some of the newer Perl API features to older versions of Perl". Isn't this the opposite direction from my situation?

Also the PPPort docs have some rough spots.
1. "the ppport.h C header file ... contains a series of macros and, if explicitly requested, functions that allow XS modules to be built using older versions of Perl". I can't see anything about how such explicit requesting is done?

2. "the old polluting ways of original Perl modules will not be supported very far into the future, and your module will almost certainly break". My module was written in the last few months, and it's not clear how any "old polluting ways" could have snuck into it from "original Perl modules"?
