# Work around warnings building Ruby 2.0 on Clang 2.x:
# pass -Wno-error=shorten-64-to-32 if the compiler accepts it.
#
# When we set CFLAGS, Ruby won't apply its default flags, though. Since clang
# builds 1.9.x and 2.x only, where -O3 is default, we can safely set that flag.
# Ensure it's the first flag since later flags take precedence.
