This breaks C90 support, not to mention K&R support.  Some committers
recently took a detour to implement C99's intmax_t and %j so that it
wouldn't take several rounds of commits to print typedefed scalar
types properly (these are library features, unlike "long long", so
they can be implemented without breaking C90 support).  The most
important part of the detour was completed in:

! RCS file: /home/ncvs/src/lib/libc/stdio/vfprintf.c,v
! Working file: vfprintf.c
! head: 1.32
! ----------------------------
! revision 1.32
! date: 2001/11/30 06:12:15;  author: fenner;  state: Exp;  lines: +233 -115
! Implement several of the c99 updates to printf(3):
!  - New length modifiers: hh, j, t, z.

%ll should not be used to print typedefed types after this.
