* unix/tcl.m4: replace all direct references to compiler by ${CC} to

			enable CC overriding at configure & make time; run
			check for visibility "hidden" with all compilers;
			quoting fixes from TEA tcl.m4.
	(SunOS-5.1x):	replace direct use of '/usr/ccs/bin/ld' in SHLIB_LD by
			'cc' compiler driver.
	* unix/configure: autoconf-2.59
