narrowest_uint_type()

const char * narrowest_uint_type ( unsigned int limit )

static

Return the name of the narrowest unsigned integer type that is guaranteed
to hold every value below LIMIT.  The generated file is compiled for the
host, which need not be the machine that runs this generator, so use the
ranges that ISO C requires rather than the ones this machine happens to
provide.  GCC hosts have at least 32-bit ints, which cover every vec
index.
