+       * breakpoint.c, findvar.c, infrun.c, putenv.c, stack.c:  Fix
+       miscellaneous comparisons of integer with NULL that elicit
+       compiler warnings about comparison of integer with pointer, when
+       NULL is ((void *) 0) rather than just a bare 0.

+       * symtab.h (struct fn_field): Add new fields `is_private',
+       `is_protected', `is_stub', making room by reducing the size of
+       `voffset'.
+       (struct fn_fieldlist): Delete the fields `private_fn_field_bits'
+       and `protected_fn_field_bits'.
+       (TYPE_FN_{PRIVATE,PROTECTED}_BITS): Deleted.
+       (SET_TYPE_FN_{PRIVATE,PROTECTED}): Deleted.
+       (TYPE_FN_{PRIVATE,PROTECTED}): Deleted.
+       (TYPE_FN_FIELD_{STUB,PRIVATE,PROTECTED}): New macros.
+       * valops.c, valprint.c, symtab.c: All callers updated.
+
+       * buildsym.c (read_struct_type): Delete the `visibility' field
+       from `struct next_fnfield', and rework code so that visibility
+       info is stored into the fn_field directly.  Also, hacked to set
+       TYPE_FN_FIELD_STUB for both static and normal member functions.
