That's not a meaningful reduction. The relevant reduction would be to
just one of the CHECK_* macro calls in the test, which would show which
macro (in the system's <stdint.h> header) has an incorrect definition.
You could then consider fixing this with a fixincludes fix for buggy
system headers (as well as fixing the headers upstream).
