This looks like a minor bug in the code, regarding which gcc14 is stricter than earlier versions.

A quick fix will be to add:

configure.cflags-append -Wno-error=incompatible-pointer-types

Or otherwise build it with gcc13.

Probably has nothing to do with powerpc specifically.

tried that, failed again, same error log.
