+# NAME
+#	makedefs 1
+# SUMMARY
+#	Postfix makefile configuration utility
+# SYNOPSIS
+#	\fBmake makefiles \fIname=value...\fR
+# DESCRIPTION
+#	The \fBmakedefs\fR command identifies the compilation
+#	environment, and emits macro definitions on the standard
+#	output stream that can be prepended to template Makefiles.
+#	These macros implement an internal interface and are subject
+#	to change without notice.
+# NAME=VALUE OVERRIDES
+# .ad
+# .fi
+#	Default settings can be overruled by specifying them as
+#	environment variables (or as name=value pairs on the "make"
+#	command line). Use quotes if variables contain whitespace
+#	or shell meta characters.
+#
+#	The command "\fBmake makefiles name=value...\fR" will replace
+#	the string \fBMAIL_VERSION\fR at the end of a value with the
+#	Postfix version (\fImajor.minor.patchlevel\fR for a stable
+#	release, \fImajor.minor-date\fR for a development release).
+#	Do not try to specify something like \fB$mail_version\fR:
+#	that produces inconsistent results with different implementations
+#	of the make(1) command.
+# .IP \fBAUXLIBS=\fIobject_library...\fR
+#	Specifies one or more non-default object libraries. Postfix
+#	3.0 and later specify some of their database library
+#	dependencies with AUXLIBS_CDB, AUXLIBS_LDAP, AUXLIBS_LMDB,
+#	AUXLIBS_MYSQL, AUXLIBS_PCRE, AUXLIBS_PGSQL, AUXLIBS_SDBM,
+#	and AUXLIBS_SQLITE, respectively.
+# .IP \fBCC=\fIcompiler_command\fR
+#	Specifies a non-default compiler. On many systems, the default
+#	is \fBgcc\fR.
+# .IP \fBCCARGS=\fIcompiler_arguments\fR
+#	Specifies non-default compiler arguments, for example, a non-default
+#	\fIinclude\fR directory.
+#	The following directives are special:
+# .RS
+# .IP \fB-DNO_DB\fR
+#	Do not build with Berkeley DB support.
+# .IP \fB-DNO_DEVPOLL\fR
+#	Do not build with Solaris /dev/poll support.
+#	By default, /dev/poll support is compiled in on platforms that
+#	are known to support it.
+# .IP \fB-DNO_DNSSEC\fR
+#	Do not build with DNSSEC support, even if the resolver
+#	library appears to support it.
+# .IP \fB-DNO_EPOLL\fR
+#	Do not build with Linux EPOLL support.
+#	By default, EPOLL support is compiled in on platforms that
+#	are known to support it.
+# .IP \fB-DNO_EAI\fR
+#	Do not build with EAI (SMTPUTF8) support. By default, EAI
+#	support is compiled in when the "pkg-config" command is
+#	found, or the deprecated "icu-config" command.
+# .IP \fB-DNO_INLINE\fR
+#	Do not require support for C99 "inline" functions. Instead,
+#	implement argument typechecks for non-(printf/scanf)-like
+#	functions with ternary operators and unreachable code.
+# .IP \fB-DNO_IPV6\fR
+#	Do not build with IPv6 support.
+#	By default, IPv6 support is compiled in on platforms that
+#	are known to have IPv6 support.
+#
+#	Note: this directive is for debugging and testing only. It
+#	is not guaranteed to work on all platforms. If you don't
+#	want IPv6 support, set "inet_protocols = ipv4" in main.cf.
+# .IP \fB-DNO_IP_CYRUS_SASL_AUTH\fR
+#	Don't pass remote SMTP client and Postfix SMTP server IP
+#	address and port information to the Cyrus SASL library.
+#	This is compatible with Postfix < 3.2.
+# .IP \fB-DNO_KQUEUE\fR
+#	Do not build with FreeBSD/NetBSD/OpenBSD/MacOSX KQUEUE support.
+#	By default, KQUEUE support is compiled in on platforms that
+#	are known to support it.
+# .IP \fB-DNO_NIS\fR
+#	Do not build with NIS or NISPLUS support. Support for NIS
+#	is unavailable on some recent Linux distributions.
+# .IP \fB-DNO_NISPLUS\fR
+#	Do not build with NISPLUS support. Support for NISPLUS
+#	is unavailable on some recent Solaris distributions.
+# .IP \fB-DNO_PCRE\fR
+#	Do not build with PCRE support.
+#	By default, PCRE support is compiled in when the \fBpcre-config\fR
+#	utility is installed.
+# .IP \fB-DNO_POSIX_GETPW_R\fR
+#	Disable support for POSIX getpwnam_r/getpwuid_r.
+# .IP \fB-DNO_SIGSETJMP\fR
+#	Use setjmp()/longjmp() instead of sigsetjmp()/siglongjmp().
+#	By default, Postfix uses sigsetjmp()/siglongjmp() when they
+#	appear to work.
+# .IP \fB-DNO_SNPRINTF\fR
+#	Use sprintf() instead of snprintf(). By default, Postfix
+#	uses snprintf() except on ancient systems.
+# .RE
+# .IP \fBDEBUG=\fIdebug_level\fR
+#	Specifies a non-default debugging level. The default is \fB-g\fR.
+#	Specify \fBDEBUG=\fR to turn off debugging.
+# .IP \fBOPT=\fIoptimization_level\fR
+#	Specifies a non-default optimization level. The default is \fB-O\fR.
+#	Specify \fBOPT=\fR to turn off optimization.
+# .IP \fBPOSTFIX_INSTALL_OPTS=\fI-option...\fR
+#	Specifies options for the postfix-install command, separated
+#	by whitespace. Currently, the only supported option is
+#	\fB-keep-build-mtime\fR.
+# .IP \fBSHLIB_CFLAGS=\fIflags\fR
+#	Override the compiler flags (typically, "-fPIC") for Postfix
+#	dynamically-linked libraries and database plugins.
+#
+#	This feature was introduced with Postfix 3.0.
+# .IP \fBSHLIB_RPATH=\fIrpath\fR
+#	Override the runpath (typically, "'-Wl,-rpath,${SHLIB_DIR}'")
+#	for Postfix dynamically-linked libraries.
+#
+#	This feature was introduced with Postfix 3.0.
+# .IP \fBSHLIB_SUFFIX=\fIsuffix\fR
+#	Override the filename suffix (typically, ".so") for Postfix
+#	dynamically-linked libraries and database plugins.
+#
+#	This feature was introduced with Postfix 3.0.
+# .IP \fBshared=yes\fR
+# .IP \fBshared=no\fR
+#	Enable (disable) Postfix builds with dynamically-linked
+#	libraries typically named $shlib_directory/libpostfix-*.so.*.
+#
+#	This feature was introduced with Postfix 3.0.
+# .IP \fBdynamicmaps=yes\fR
+# .IP \fBdynamicmaps=no\fR
+#	Enable (disable) Postfix builds with the configuration file
+#	$meta_directory/dynamicmaps.cf and dynamically-loadable
+#	database plugins typically named postfix-*.so.*.  The setting
+#	"dynamicmaps=yes" implicitly enables Postfix dynamically-linked
+#	libraries.
+#
+#	This feature was introduced with Postfix 3.0.
+# .IP \fBpie=yes\fR
+# .IP \fBpie=no\fR
+#	Enable (disable) Postfix builds with position-independent
+#	executables, on platforms where this is supported.
+#
+#	This feature was introduced with Postfix 3.0.
+# .IP \fIinstallation_parameter\fB=\fIvalue\fR...
+#	Override the compiled-in default value of the specified
+#	installation parameter(s). The following parameters are
+#	supported in this context:
+#
+#	command_directory config_directory daemon_directory
+#	data_directory default_database_type html_directory
+#	mail_spool_directory mailq_path manpage_directory meta_directory
+#	newaliases_path queue_directory readme_directory sendmail_path
+#	shlib_directory openssl_path
+#
+#	See the postconf(5) manpage for a description of these
+#	parameters.
+#
+#	This feature was introduced with Postfix 3.0.
+# .IP \fBWARN=\fIwarning_flags\fR
+#	Specifies non-default gcc compiler warning options for use when
+#	"make" is invoked in a source subdirectory only.
+# LICENSE
