I don't recall seeing these, but I think the latest version of AIX we're building on is 7.1. And it looks like we're still using 1.1.1k (must not have needed the fixes from 1.1.1l). Also, I'm no longer the person doing our UNIX builds.

This appears to be because _ALL_SOURCE isn't defined.

The ldinfo_next error is a cascade from the earlier errors reported against sys/ldr.h. I have no idea at the moment why you're getting those; it's not obvious from a quick look at the header. And at least the one on the AIX 7.1 box I checked hasn't changed since 2014.

Try editing the Makefile and adding -D_ALL_SOURCE to see if that fixes the RTLD_MEMBER error. It might also have an effect on the ldr.h errors. If so, the Configure entry for aix-cc might need an update.
