Cannot compile in AIX using c-compiler

I looked at the two log files, and I see no indication of errors, at least to my untrained eye. The first is a long list of possible versions of the C compiler for many platforms, and it seems to identify that this is AIX
with no problems… the second confirms that it knows it is AIX, and seems to show no errors… the output file a.out is binary, and scanning it I see nothing obvious pointing to the problem…

thanks!
