 # Define MOZILLA_SHA1 environment variable when running make to make use of
 # a bundled SHA1 routine coming from Mozilla. It is GPL'd and should be fast
 # on non-x86 architectures (e.g. PowerPC), while the OpenSSL version (default
 # choice) has very fast version optimized for i586.
 #
 # Define NO_OPENSSL environment variable if you do not have OpenSSL. You will
 # miss out git-rev-list --merge-order. This also implies MOZILLA_SHA1.
 #
 # Define NO_CURL if you do not have curl installed.  git-http-pull is not
 # built, and you cannot use http:// and https:// transports.
 #
 # Define PPC_SHA1 environment variable when running make to make use of
 # a bundled SHA1 routine optimized for PowerPC.


 # Define COLLISION_CHECK below if you believe that SHA1's
 # 1461501637330902918203684832716283019655932542976 hashes do not give you
 # sufficient guarantee that no collisions between objects will ever happen.

 # DEFINES += -DCOLLISION_CHECK

 # Define USE_NSEC below if you want git to care about sub-second file mtimes
 # and ctimes. Note that you need recent 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).

 # DEFINES += -DUSE_NSEC

 # Define USE_STDEV below if you want git to care about the underlying device
 # change being considered an inode change from the update-cache perspective.
