  On other systems (at least on windows and AFAIK on linux / solaris as 
well) argv[0] is the string how the program was invoked. This is 
different; if the program was invoked with full or relative path, then I 
can get the info I want. However, if the program is found on PATH argv[0] 
is pretty useless. Ok, I could replicate the functionality of "which" 
command to find out where the program was, but this seems clumsy.
  Or is this different on os-x so that argv[0] always contains the full 
path to the executable?
