--- Comment #1 from Alan Modra <amodra at gmail dot com> ---
One proper solution is to implement the equivalent warning disable for clang
that this does for gcc:
#if GCC_VERSION >= 4003
# pragma GCC diagnostic push
# pragma GCC diagnostic ignored "-Wtype-limits"
#endif
The "if" in question isn't always false when "long" is the same size as
"unsigned int", which is generally true on 32-bit hosts and even true for some
64-bit host compilers.
