You might try getting the macro library to do this:

not preprocessed:

#define SOME_MACRO \
{\
line1();  \
line2();  \
}

// the following is at line n
int main() SOME_MACRO

have the library replace it with:

int main()
#line n
{
#line n
line1();
#line n
line2();
#line n
}

Then use this information in your AST?

I don't know how hard it would be.
