It seems the preprocessor in BGBCC is likely not entirely conformant in 
this case...

If given a recursive macro, it will most likely just explode and 
probably crash the compiler...

Mostly as it handles macro-expansion by looping over the line and 
performing macro-substitutions until no more substitutions are seen, at 
which point it emits the line to the output buffer and moves on to the 
next line.
