Thanks for the patch.
Could there be a method for checking this in one of AIX's header files?
If not, I'll do as you suggest -- but I'd rather use strstr than strtok.
Here's a bit of code that should be functionally equivalent to yours,
assuming the fields are guaranteed to be comma-separated, with no white
space. Would you please test it?
