# NAME
#	makedefs 1
# SUMMARY
#	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.
#
#	Default settings can be overruled by specifying them as
#	environment variables. Use quotes if variables contain
#	whitespace or shell meta characters.
# .IP \fBAUXLIBS=\fIobject_library...\fR
#	Specifies one or more non-default object libraries.
# .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_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_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_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.
# .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_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_SIGSETJMP\fR
#	Use setjmp()/longjmp() instead of sigsetjmp()/siglongjmp().
#	By default, Postfix uses sigsetjmp()/siglongjmp() when they
#	appear to work.
# .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 \fBWARN=\fIwarning_flags\fR
#	Specifies non-default gcc compiler warning options for use when
#	"make" is invoked in a source subdirectory only.
