/* One of the goals of this test is to detect potential issues with the
* following case in user code:
*
* #include <some_lib.h>
* #include <stdint.h>
* #define MPFR_USE_INTMAX_T
* #include <mpfr.h>
*
* where some_lib.h has "#include <mpfr.h>". So, the mpfr.h header file
* is included multiple times, a first time without <stdint.h> before,
* and a second time with <stdint.h> support. We need to make sure that
* the second inclusion is not a no-op due to some #include guard. This
* was fixed in r7320.
*
* With mini-gmp, mpfr-impl.h is included first, but this should not
* affect this test.
*
* Note: If _MPFR_EXP_FORMAT == 4 (which is never the case by default),
* a part of the above check is not done because <stdint.h> is included
* before the first mpfr.h inclusion (see above).
