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
         libraries  = -L/usr/vac/lib,-lxlopt,-lxlipa,-lxl,-lpthreads,-lc
         proflibs   = -L/lib/profiled,-L/usr/lib/profiled

         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
