[antlr-interest] [C target] #define clashes: would it be possible to add ANTLR_ prefix to automatically generated macros?

I have been using ANTLR C target with success for several months...
until I included a file from the BOOST C++ library set.

One of my ANTLR rule is DOMAIN.
ANTLR lexer (C target) automatically generates the macro "#define DOMAIN 4".
I include a BOOST header file (for hashtable support) after the lexer
header file. Then, I am not able to parse the DOMAIN rule because
BOOST redefines it to 1!

I think BOOST should prefix its macros, but it would be safer if ANTLR
added some prefix to macros it generates in header files.

What do you think about it?
