Also, to you and anyone else with access to AIX: I'd be happy to figure
these issues out pro-actively if you give me a login to an AIX
machine. I promise not to do anything except compile/debug/test git on
it.
The GCC compile farm <http://gcc.gnu.org/wiki/CompileFarm> has a machine
running AIX, and is free to use for anyone working on free software.
My goal is less "to work on", more, "to package" and/or "to work with". Most others, including IBM, seem to use gcc as compiler - which is fine. However, on AIX I often see side-effects introduced by the GNU run-time environment needed on top of the xlc.rte provided as part of AIX.

In any case - my testing is using the xlc complier - so there are syntax differences. the compiler has many modes - by default I use 'xlc_r' that has the following default settings:
xlc_r:  use        = DEFLT_C
        crt        = /lib/crt0.o
        mcrt       = /lib/mcrt0.o
        gcrt       = /lib/gcrt0.o

        options    = -qlanglvl=extc99,-qcpluscmt,-qkeyword=inline,-qalias=ansi,-qthreaded,-D_THREAD_SAFE,-D__VACPP_MULTI__

DEFLT_C (for the curious, the default options is perhaps most interesting) is:
* common definitions

DEFLT_C:
        use           =DEFLT
        xlurt_cfg_path=/usr/vac/urt
        xlurt_cfg_name=urt_client.cfg
