The manual for gcc 3.2.3's preprocessor is here:
http://gcc.gnu.org/onlinedocs/gcc-3.2.3/cpp/

The C preprocessor is only intended for use with C code. 
    '#node "node.file"' is not C. So I don't think what you are trying
    to do is supported, but if you read the manual you may find a way
    to do it.
