# Define V=1 to have a more verbose compile.
# Define V=2 to have an even more verbose compile.
#
# 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 MOZILLA_SHA1.
#
# Define CURLDIR=/foo/bar if your curl header and library files are in
# /foo/bar/include and /foo/bar/lib directories.
#
# Define EXPATDIR=/foo/bar if your expat header and library files are in
# /foo/bar/include and /foo/bar/lib directories.
#
# 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 (latest Cygwin -- will be fixed soonish).
#
# 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_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_SYS_SELECT_H if you don't have sys/select.h.
#
# Define NO_SYMLINK_HEAD if you never want .perf/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 PERF 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 PERF 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 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 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 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 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.
# cygwin.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 perf 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 perf 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.
#
# 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 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 NO_EXTERNAL_GREP if you don't want "perf grep" to ever call
# your external grep (e.g., if your system lacks grep, if its grep is
# broken, or spawning external process is slower than built-in grep perf has).
#
# Define LDFLAGS=-static to build a static binary.
#
# Define EXTRA_CFLAGS=-m64 or EXTRA_CFLAGS=-m32 as appropriate for cross-builds.
#
# Define NO_DWARF if you do not want debug-info analysis feature at all.
