I'm talking with Oracle Solaris Engineering and they're amenable to
making the int8_t change from char to signed char.
To assess the possible impact, the plan is to compare the public

The tests that GCC's internal notion of the types agrees with the headers are
in gcc.dg/c99-stdint-5.c and gcc.dg/c99-stdint-6.c.
