* unix/configure: add caching, use AC_CACHE_CHECK instead of

	* unix/configure.in: AC_CACHE_VAL where possible, consistent message
	* unix/tcl.m4:       quoting, sync relevant tclconfig/tcl.m4 changes and
	gratuitous formatting differences, fix SC_CONFIG_MANPAGES with default
	argument, Darwin improvements to SC_LOAD_*CONFIG.
