No. limits.h has always been a standard header in ANSI C.

Maybe. But inttypes.h exists only in C99, not in earlier standards.
In addition, implementations MUST NOT define uint8_t and int8_t if the
processor does not have a native signed and unsigned integer type
that's exactly 8 bits wide. The most portable way (in C99, anyway) is
to use uint_least8_t and int_least8_t (or uint_fast8_t and
int_fast8_t).
