Yes, technically you are right, and replacing ULONG with sal_uIntPtr
would be the safest choice.

My objection is mainly on the ground that using a type that is
suggestive of pointer value storage for values that are purely numerical
(such as the number format ID's) is, although safe from technical point
of view, not desirable.  And in most places in our code base where ULONG
is used, 32-bit integer range should be sufficient.  I'm sure there are
places where the real behavior of long is expected, so we need to go on
a case-by-case basis for this, but in the area where Soeren made his
changes, 32-bit range is more than sufficient.

Actually, I've been a proponent of these data types myself.  So I
personally would much prefer using these types over sal_Foo data types.
So, no objection there from me. :-)
