Those should have a semi-colon at the end of the declaration, so this is a
simple way to check it it's the declaration of a pointer to function or a
function. If the next token is a ';' you have a pointer to function, if it
is ( id * ';' )* '{' it's a function. This of course modulo any nifty CPP
#ifdef's and comments. (I can't really imagine you can do a full blown job
before you preprocess the file. Any token could really be MACRO and blow
all your assumptions about the code to pieces. But for most code, the
regexp approach should do the job.)
