# Note to self: on 64-bit, we can ignore this warning from configure:

# What it really means is that, on 64-bit, we don't need any extra
# CFLAGS to enable large file (64-bit off_t) support. On 32-bit,
# we get "yes", and the appropriate flags are used automatically.
# If this were to fail on 32-bit, wput wouldn't be able to handle
# files >= 2GB. Quite possibly, nobody would ever notice...
