       Proposal Attached: Y_ Yes __ No, but what's your interest?
       Abstract:

       It is dangerous for future standardization to reserve a small,
       fixed set of names in a header that would be a likely candidate for
       future expansion in a new version of C.
       
       Proposal:
	
       Insert a new paragraph, to be somewhere around 7.19.2,
       reading

	7.19.2 Integral types <inttypes.h>

	Type names beginning with 'int' or 'uint' and ending in _t
	may be added to the types defined in the <inttypes.h> header.
	Macro names beginning with 'INT' or 'UINT' and ending in '_MAX'
	or '_MIN', or macro names beginning with 'PRI' or 'SCN' followed
	by any printf or scanf format character suitable for formatting
	integer-typed objects, may be added to the macros defined in the
	<inttypes.h> header.

       (Apologies if I missed anything, or painted with too broad a brush.)

       This will leave C2K room for int128_t, int_nearly64_t, and
       whatever other things become desirable in the future.  It will
       also leave room for implementors to extend the standard in a
       reasonable and comprehensible fashion.

       It would be nice if we could specify that the new typedefs need
       to have the "obvious" meanings, but I am unable to see how to
       phrase this request.
