This functionality will be defined in the next version of the ISO C
standard, in the header inttypes.h. Since this is an international
standards body, the naming they use cannot be consistent with existing
practices (;) :
(e.g., uint32_t or int_least64_t)

My vote would be for using those.

The drafts are available on ftp.dkuug.dk somewhere (I usually just get
there from http://www.lysator.liu.se/c.)
