# The default target of this Makefile is...
all::

# Define V=1 to have a more verbose compile.
#
# Define SHELL_PATH to a POSIX shell if your /bin/sh is broken.
#
# Define SANE_TOOL_PATH to a colon-separated list of paths to prepend
# to PATH if your tools in /usr/bin are broken.
#
# Define SOCKLEN_T to a suitable type (such as 'size_t') if your
# system headers do not define a socklen_t type.
#
# Define INLINE to a suitable substitute (such as '__inline' or '') if git
# fails to compile with errors about undefined inline functions or similar.
#
# Define SNPRINTF_RETURNS_BOGUS if your are on a system which snprintf()
# or vsnprintf() return -1 instead of number of characters which would
# have been written to the final string if enough space had been available.
#
# Define FREAD_READS_DIRECTORIES if your are on a system which succeeds
# when attempting to read from an fopen'ed directory.
#
# Define NO_OPENSSL environment variable if you do not have OpenSSL.
# This also implies BLK_SHA1.
#
# Define NO_CURL if you do not have libcurl 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 EXPATDIR=/foo/bar if your expat header and library files are in
# /foo/bar/include and /foo/bar/lib directories.
#
# Define HAVE_PATHS_H if you have paths.h and want to use the default PATH
# it specifies.
#
# Define NO_D_INO_IN_DIRENT if you don't have d_ino in your struct dirent.
#
# Define NO_D_TYPE_IN_DIRENT if your platform defines DT_UNKNOWN but lacks
# d_type in struct dirent (Cygwin 1.5, fixed in Cygwin 1.7).
#
# Define NO_C99_FORMAT if your formatted IO functions (printf/scanf et.al.)
# do not support the 'size specifiers' introduced by C99, namely ll, hh,
# j, z, t. (representing long long int, char, intmax_t, size_t, ptrdiff_t).
# some C compilers supported these specifiers prior to C99 as an extension.
#
# Define NO_STRCASESTR if you don't have strcasestr.
#
# Define NO_MEMMEM if you don't have memmem.
#
# Define NO_STRLCPY if you don't have strlcpy.
#
# Define NO_STRTOUMAX if you don't have strtoumax in the C library.
# If your compiler also does not support long long or does not have
# strtoull, define NO_STRTOULL.
#
# Define NO_SETENV if you don't have setenv in the C library.
#
# Define NO_UNSETENV if you don't have unsetenv in the C library.
#
# Define NO_MKDTEMP if you don't have mkdtemp in the C library.
#
# Define NO_MKSTEMPS if you don't have mkstemps in the C library.
#
# Define NO_STRTOK_R if you don't have strtok_r in the C library.
#
# Define NO_LIBGEN_H if you don't have libgen.h.
#
# Define NEEDS_LIBGEN if your libgen needs -lgen when linking
#
# Define NO_SYS_SELECT_H if you don't have sys/select.h.
#
# Define NO_SYMLINK_HEAD if you never want .git/HEAD to be a symbolic link.
# Enable it on Windows.  By default, symrefs are still used.
#
# Define NO_SVN_TESTS if you want to skip time-consuming SVN interoperability
# tests.  These tests take up a significant amount of the total test time
# but are not needed unless you plan to talk to SVN repos.
#
# Define NO_FINK if you are building on Darwin/Mac OS X, have Fink
# installed in /sw, but don't want GIT to link against any libraries
# installed there.  If defined you may specify your own (or Fink's)
# include directories and library directories by defining CFLAGS
# and LDFLAGS appropriately.
#
# Define NO_DARWIN_PORTS if you are building on Darwin/Mac OS X,
# have DarwinPorts installed in /opt/local, but don't want GIT to
# link against any libraries installed there.  If defined you may
# specify your own (or DarwinPort's) include directories and
# library directories by defining CFLAGS and LDFLAGS appropriately.
#
# Define BLK_SHA1 environment variable if you want the C version
# of the SHA1 that assumes you can do unaligned 32-bit loads and
# have a fast htonl() function.
#
# Define PPC_SHA1 environment variable when running make to make use of
# a bundled SHA1 routine optimized for PowerPC.
#
# Define NEEDS_CRYPTO_WITH_SSL if you need -lcrypto when using -lssl (Darwin).
#
# Define NEEDS_SSL_WITH_CRYPTO if you need -lssl when using -lcrypto (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 NEEDS_RESOLV if linking with -lnsl and/or -lsocket is not enough.
# Notably on Solaris hstrerror resides in libresolv and on Solaris 7
# inet_ntop and inet_pton additionally reside there.
#
# Define NO_MMAP if you want to avoid mmap.
#
# Define NO_PTHREADS if you do not have or do not want to use Pthreads.
#
# Define NO_PREAD if you have a problem with pread() system call (e.g.
# cygwin1.dll before v1.5.22).
#
# Define NO_FAST_WORKING_DIRECTORY if accessing objects in pack files is
# generally faster on your platform than accessing the working directory.
#
# Define NO_TRUSTABLE_FILEMODE if your filesystem may claim to support
# the executable mode bit, but doesn't really do so.
#
# Define NO_IPV6 if you lack IPv6 support and getaddrinfo().
#
# Define NO_SOCKADDR_STORAGE if your platform does not have struct
# sockaddr_storage.
#
# Define NO_ICONV if your libc does not properly support iconv.
#
# Define OLD_ICONV if your library has an old iconv(), where the second
# (input buffer pointer) parameter is declared with type (const char **).
#
# Define NO_DEFLATE_BOUND if your zlib does not have deflateBound.
#
# Define NO_R_TO_GCC_LINKER if your gcc does not like "-R/path/lib"
# that tells runtime paths to dynamic libraries;
# "-Wl,-rpath=/path/lib" is used instead.
#
# 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).
#
# Define USE_ST_TIMESPEC if your "struct stat" uses "st_ctimespec" instead of
# "st_ctim"
#
# Define NO_NSEC if your "struct stat" does not have "st_ctim.tv_nsec"
# available.  This automatically turns USE_NSEC off.
#
# Define USE_STDEV below if you want git to care about the underlying device
# change being considered an inode change from the update-index perspective.
#
# Define NO_ST_BLOCKS_IN_STRUCT_STAT if your platform does not have st_blocks
# field that counts the on-disk footprint in 512-byte blocks.
#
# Define ASCIIDOC8 if you want to format documentation with AsciiDoc 8
#
# Define DOCBOOK_XSL_172 if you want to format man pages with DocBook XSL v1.72
# (not v1.73 or v1.71).
#
# Define ASCIIDOC_NO_ROFF if your DocBook XSL escapes raw roff directives
# (versions 1.72 and later and 1.68.1 and earlier).
#
# Define GNU_ROFF if your target system uses GNU groff.  This forces
# apostrophes to be ASCII so that cut&pasting examples to the shell
# will work.
#
# Define NO_PERL_MAKEMAKER if you cannot use Makefiles generated by perl's
# MakeMaker (e.g. using ActiveState under Cygwin).
#
# Define NO_PERL if you do not want Perl scripts or libraries at all.
#
# Define NO_PYTHON if you do not want Python scripts or libraries at all.
#
# Define NO_TCLTK if you do not want Tcl/Tk GUI.
#
# The TCL_PATH variable governs the location of the Tcl interpreter
# used to optimize git-gui for your system.  Only used if NO_TCLTK
# is not set.  Defaults to the bare 'tclsh'.
#
# The TCLTK_PATH variable governs the location of the Tcl/Tk interpreter.
# If not set it defaults to the bare 'wish'. If it is set to the empty
# string then NO_TCLTK will be forced (this is used by configure script).
#
# Define INTERNAL_QSORT to use Git's implementation of qsort(), which
# is a simplified version of the merge sort used in glibc. This is
# recommended if Git triggers O(n^2) behavior in your platform's qsort().
#
# Define UNRELIABLE_FSTAT if your system's fstat does not return the same
# information on a not yet closed file that lstat would return for the same
# file after it was closed.
#
# Define OBJECT_CREATION_USES_RENAMES if your operating systems has problems
# when hardlinking a file to another name and unlinking the original file right
# away (some NTFS drivers seem to zero the contents in that scenario).
#
# Define NO_CROSS_DIRECTORY_HARDLINKS if you plan to distribute the installed
# programs as a tar, where bin/ and libexec/ might be on different file systems.
#
# Define USE_NED_ALLOCATOR if you want to replace the platforms default
# memory allocators with the nedmalloc allocator written by Niall Douglas.
#
# Define NO_REGEX if you have no or inferior regex support in your C library.
#
# Define JSMIN to point to JavaScript minifier that functions as
# a filter to have gitweb.js minified.
#
# Define CSSMIN to point to a CSS minifier in order to generate a minified
# version of gitweb.css
#
# Define DEFAULT_PAGER to a sensible pager command (defaults to "less") if
# you want to use something different.  The value will be interpreted by the
# shell at runtime when it is used.
#
# Define DEFAULT_EDITOR to a sensible editor command (defaults to "vi") if you
# want to use something different.  The value will be interpreted by the shell
# if necessary when it is used.  Examples:
#
#   DEFAULT_EDITOR='~/bin/vi',
#   DEFAULT_EDITOR='$GIT_FALLBACK_EDITOR',
#   DEFAULT_EDITOR='"C:\Program Files\Vim\gvim.exe" --nofork'
#
# Define COMPUTE_HEADER_DEPENDENCIES if your compiler supports the -MMD option
# and you want to avoid rebuilding objects when an unrelated header file
# changes.
#
# Define CHECK_HEADER_DEPENDENCIES to check for problems in the hard-coded
# dependency rules.
#
# Define NATIVE_CRLF if your platform uses CRLF for line endings.
