Not really. The main thing is that many symbols in gram.y eventually
get turned into a #define and if the symbol is a normal looking word
that may be used in another context it's common to suffix it with a _P
(the P stands for something but I forget what. Predicate?). That way
you don't run into unexpected surprises when it compiles with other
headers...
Have a nice day,
