commit ff3eda68ceb2e2bb8f48e3faceb96076c3e85c20
Author: Darren Tucker <dtucker at dtucker.net>
Date:   Thu Aug 31 23:02:35 2023 +1000

    Set LLONG_MAX for C89 test.
    
    If we don't have LLONG_MAX, configure will figure out that it can get it
    by setting -std=gnu99, at which point we won't be testing C89 any more.
    To avoid this, feed it in via CFLAGS.
