Sorry if I misunderstood, but why is this a problem? #defining a macro
which takes arguments, such as:

  #define clear(bmp) allegro_clear(bmp)

would not affect structure members:

  struct abc {
     int clear;
  };

  printf("%d\n", offsetof(struct abc, clear));

The printf() statement above would *not* expand to:

  printf("%d\n", offsetof(struct abc, allegro_clear));

Bye for now,
