In light of what pan writes, and in light of the below message which I just
posted on comp.std.c++ (where it did not yet get past moderation, so did not
receive any answers yet):  Maybe the best solution to the SalGtkFilePicker.cxx
and salnativewidgets-gtk.cxx problems in issue 66686 is to *do* apply the
corresponding patches from issue 66686 (independently of removing #define NULL
from tools/inc/solar.h).

Ellipsis and null pointer constant

Is my understanding correct that with

  void f(int, ...);
  f(1, 0);
  f(2, NULL);
  f(3, static_cast< int * >(0));

neither the first nor the second call portably pass a null pointer value as
second argument to f (which f could obtain with va_arg(ap, int)), and that
instead something like the third form must be used?

I assume so, as pointer conversion (which null pointer constant to null pointer
value is, 4.10/1) is not mentioned in 5.2.2/7.

(And I guess that the leeway to allow NULL to be defined as any of 0, 0L, etc.
is there so that the second form *does* work in practice.  Is that right?)
