One area of concern is if you are not tracking file, how can you get the right defines for a given source file line? If you have:


  #include <foo.h>
  #define FOO printf
  int main ()
      return 0; // Stop here and run: FOO("hello world\n")
  #undef FOO

But in foo.h you have:
#define FOO puts

// nothing
// nothing
// nothing
// nothing

#undef FOO

  Do you currently correctly have the following in your macros if stopped at the return statement in main?

#define FOO puts    <<< from foo.h
#undef FOO <<< from foo.h
#define FOO print <<< from main.c

  Both foo definitions will be on line 1, and we will be stopped on line 5 of main.c, but if we don't know that the entries from foo.h come from foo.h we might accidentally include these statements?
