That would tend to increase namespace pollution, especially if done before the C99 infrastructure is implemented. > ISO/IEC 9899:1999(E) > 7.18.1.1 Exact-width interger types > > 1 The typedef name intN_t designates a signed integer type with width N, > no padding bits, and a two's complement representation.

The headers that declare the ntohl functions (<arpa/inet.h> and <netinet/in.h> in POSIX.1-200x) are not permitted to include <stdint.h>.
