Update GNU M4 to 1.4.9

1.  Summary

	This fast-track increments the version of GNU M4 (GM4) in Solaris
	from 1.4.2 to 1.4.9.

	Patch release binding is requested.

2.  Discussion

	GM4 is an implementation of the traditional Unix macro processor.
	It is an open-source project maintained by a community outside
	Sun Microsystems.

	Other implementations of M4 are also includeded in Solaris at
	/usr/bin/m4 (linked from /usr/ccs/bin/m4) and /usr/xpg4/bin/m4.

	One of the biggest users of GM4 is GNU Autoconf.  The version of
	GNU Autoconf in Solaris (2.61) states that it requires GM4 version
	1.4.7 or later.  A number of projects such as JDS and the recently
	approved "Certificate & PKCS#11 PAM module" [1] cannot build with
	the version of GM4 currently in Solaris.

	The latest stable version of GM4 is 1.4.11.  However, since 1.4.10
	GM4 has been released with the GPLv3 license, which is not
	approved for Solaris.  Therefore, this proposal integrates the
	latest version of GM4 that was released under GPLv2, 1.4.9.

	As with the previously integrated version, GM4 1.4.9 consists
	of the /usr/bin/gm4 command; links to this command from
	/usr/gnu/bin/m4 and /usr/sfw/bin/gm4; and an infodoc manual.
	Newly added in this version is a manpage.  This version also
	utilises /usr/lib/charset.alias, a table of character encoding
	aliases, which is provided by glib.

	Numerous bugs and RFEs have been fixed from the earlier version,
	including a number of minor changes to the command-line parameters.
	APPENDIX A shows the full usage syntax for versions 1.4.2 and
	1.4.9.  Also, details of all the changes since 1.4.2 are shown
	in APPENDIX B, taken from the GM4 Release Notes and ChangeLog.

	As is currently the practise in SFW, the info doc manual will
	be moved from the SUNWsfinf package to the "parent" package,
	SUNWgm4.

	GM4 uses /usr/lib/charset.alias, a Private interface provided
	by glib in GNOME [2] & [3].  A contract governing this usage has
	also been submitted [4] and this case is dependent on that contract.
