Patch to add BeOS support in libio and libstdc++

[Jason Merrill <jason at cygnus dot com>]

libio:
2000-01-12  Fred Fish <fnf@be.com>

	* configure.in (*-*-beos*): Recognize.
	* config/beos.mt: New file.

libstdc++:
2000-01-12  Fred Fish  <fnf@be.com>

	* Makefile.in (SHOPT): New macro, flag to ld to create
	shared library.  Defaults to "-shared".
	(SHLIB): Use new SHOPT rather than hardcoded "-shared".
	* configure.in: While configuring for *-*-beos*, if
	--enable-shared is given, add beos.ml to list of makefile
	frags.
	* config/beos.ml: New file.
