C++ definition of NULL

[David Edelsohn]

	Again, this is a bug in egcs-1.1 which is fixed in the current
development snapshots.  As I said in the original reply, the fix appears
to be too involved to include in egcs-1.1.2 (I already requested that it
be added and the discussion resulted that it is too dangerous).

	egcs-1.1.1 -ansi option will make NULL an integral mode but it
also enables other features, unfortunately.
