I changed the LIBOBJS in src/Makefile.global and put the #undef after
the #define in src/include/pg_config.h.

But unfortunately that's only half of the world domaination. I still
got:

hba.c: In function `ident_unix':
hba.c:1411: storage size of `peercred' isn't known
hba.c:1411: warning: unused variable `peercred'
make[3]: *** [hba.o] Error 1

Yep. That's the other half!

Not neccessary. It compiled and linked.

Thanks, Tom.
