I've done some digging now: <inttypes.h>/<sys/int_types.h> were introduced into Solaris 2.6 (the file dates from Jul 16 1997), way before the C99 standard was finalized. I've looked around the WG14 archive, and some drafts after that date (N737 (1997-06-26), N788 (1997-11-17), N851 (1998-09-22)) do have the `signed integer type' wording. Unfortunately, all of the previous ones (which would have been the basis of the Solaris implementation) are no longer available.
