#
# -DNSEC if you want git to care about sub-second file mtimes and ctimes.
# Note that you need some new glibc (at least >2.2.4) for this, and it will
# BREAK YOUR LOCAL DIFFS! show-diff and anything using it will likely randomly
# break unless your underlying filesystem supports those sub-second times
# (my ext3 doesn't).
