This tends to be the nicer way to do it these days.
Biggest advantage is that you get type checking with a const which 
you don't get with a #define.
Been so long since I used pure C (vs C++) compilers, that I'm not 
sure whether const ever made it into the C standard, or if it is 
still a C++ extension. Well supported, though. Works in all the 
compilers I use.
