Problem Statement : Given a C file which has several macros defined (eg.
#define MACRO 10) . I need to know what all macros are defined and their
usage point(eg. line number) in the code.
Need to know this information during or after gcc pre-processing phase.
Possible solution may dump this macro information in some file.
Is there any way that gcc can dump this information and if yes how?

gcc -E -dD source.c | grep MACRO

Hi Jonathan , The problem is that i do not have the list of macros with me ,
so using grep is not going to work . . and also I need the line number
where it is resolved in source code(Even if i try to grep for known macros
, it will not be possible because they get resolved).
