Officially, in stdint.h, cf.
http://www.opengroup.org/onlinepubs/009695399/basedefs/stdint.h.html

Some folks prefer to include <inttypes.h> instead, because inttypes.h is
known to be more portable than stdint.h (some systems have inttypes.h
but don't have stdint.h), and inttypes.h is supposed to include stdint.h
cf.
http://www.opengroup.org/onlinepubs/009695399/basedefs/inttypes.h.html

Some packages (bogusly) rely on sys/types.h providing uint<N>_t, because
some OSes (namely Linux and BSD) also provide them there.

However, this behavior doesn't conform to current standards and
therefore should not be relied upon, cf.
