 104# Define MOZILLA_SHA1 environment variable when running make to make use of
 105# a bundled SHA1 routine coming from Mozilla. It is GPL'd and should be fast

 135# sufficient guarantee that no collisions between objects will ever happen.
 136#
 137# Define USE_NSEC below if you want git to care about sub-second file mtimes
 138# and ctimes. Note that you need recent glibc (at least 2.2.4) for this, and
 139# it will BREAK YOUR LOCAL DIFFS! show-diff and anything using it will likely
 140# randomly break unless your underlying filesystem supports those sub-second
 141# times (my ext3 doesn't).
 142#
 143# Define USE_STDEV below if you want git to care about the underlying device
 144# change being considered an inode change from the update-cache perspective.
