17 * The 32bit libc contains special variants of all printf functions
18 * for a strict C89 environment where intmax_t is only 32 bits wide.
19 * These handle intmax_t arguments ('j' length modifier) accordingly.
20 *
21 * Since our feature-tests header assumes that if __GNUC__ is defined,
22 * then we also always have a long long type, so it is used for intmax_t
23 * when compiling with gcc even with -std=c89 -pedantic. To work around
24 * this, allowing this test to actually do what it needs to do based on
25 * how it is compiled, we undef __GNUC__ here.
