Myers <jsm28 at gcc dot gnu.org> --- > 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. Ah, now I remember: they had to be adjusted back in the day for various omissions on Solaris and Tru64 UNIX. During my recent test bootstrap, they didn't show up because I had changed <sys/int_types.h> and sol2.h's INT8_TYPE etc. in lockstep, so no inconsistencies occured.
