 # 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 and
 # git-http-push are not built, and you cannot use http:// and https://
 # transports.
 #
 # Define CURLDIR=/foo/bar if your curl header and library files are in
 # /foo/bar/include and /foo/bar/lib directories.
 #
 # Define NO_EXPAT if you do not have expat installed.  git-http-push is
 # not built, and you cannot push using http:// and https:// transports.
 #
 # Define NO_STRCASESTR if you don't have strcasestr.
 #
 # Define PPC_SHA1 environment variable when running make to make use of
 # a bundled SHA1 routine optimized for PowerPC.
 #
 # Define ARM_SHA1 environment variable when running make to make use of
 # a bundled SHA1 routine optimized for ARM.

 # 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_MMAP if you want to avoid mmap.
 #
 # Define WITH_OWN_SUBPROCESS_PY if you want to use with python 2.3.
 #
 # Define NO_IPV6 if you lack IPv6 support and getaddrinfo().
 #
 # 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.

 # 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).
