I find it weird that it did not detect your ccversion

You are using xlc_r, which is fine, but you specify the full compiler
instead of setting your $PATH to include the xlc_r location

1. Do you have /etc/vac.cfg.131 (or alike)
2. Do you (also) have other versions of xlc installed?

What is the section for xlc_r in /etc/vac.cfg** (if you have it?

For my AIX-5 with vac-7 it looks like this:

* standard c compiler aliased as xlc_r (71 Threads)
xlc_r:  use        = DEFLT_C
        crt        = /lib/crt0.o
        mcrt       = /lib/mcrt0.o
        gcrt       = /lib/gcrt0.o
        libraries  = -L/usr/vac/lib,-lxlopt,-lxlipa,-lxl,-lpthreads,-lc
        proflibs   = -L/lib/profiled,-L/usr/lib/profiled
        hdlibs     = -L/usr/vac/lib,-lhmd
        options    = -qlanglvl=extc99,-qcpluscmt,-qkeyword=inline,-qalias=ansi,-qthreaded,-D_THREAD_SAFE,-D__VACPP_MULTI__

As you can see, there are "hidden" options that do not show in -V
