# 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 NEEDS_SSL_WITH_CRYPTO if you need -lcrypto with -lssl (Darwin).
#
# Define NEEDS_LIBICONV if linking with libc is not enough (Darwin).
#
# Define NEEDS_SOCKET if linking with libc is not enough (SunOS,
# Patrick Mauritz).
#
# Define NO_GETDOMAINNAME if your library lack it (SunOS, Patrick Mauritz).
#
# 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.
