# Define NO_TCLTK if you do not want Tcl/Tk GUI.

-# Define SANE_TEXT_GREP to "-a" if you use recent versions of GNU grep
-# and egrep that are pickier when their input contains non-ASCII data.
-#
# 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'.
# Define NEEDS_LIBRT if your platform requires linking with librt (glibc version
# before 2.17) for clock_gettime and CLOCK_MONOTONIC.
#
-# Define USE_PARENS_AROUND_GETTEXT_N to "yes" if your compiler happily
-# compiles the following initialization:
-#
-# static const char s[] = ("FOO");

-# and define it to "no" if you need to remove the parentheses () around the

# Define HAVE_BSD_SYSCTL if your platform has a BSD-compatible sysctl function.
#
# Define HAVE_GETDELIM if your system has the getdelim() function.
# the global variable _wpgmptr containing the absolute path of the current

#
+# INSTALL_STRIP can be set to "-s" to strip binaries during installation,

+#
# Define GENERATE_COMPILATION_DATABASE to "yes" to generate JSON compilation
