	* config/i386/32/sfp-machine.h (FP_HANDLE_EXCEPTIONS): Support Sun
	assembler syntax.

	gcc:
	* config.gcc (i[34567]86-*-solaris2*): Default with_arch_32 to
	pentiumpro on Solaris 8/x86 with Sun as.
	* configure.ac (gcc_cv_as_hidden): Check for Solaris 9/x86 as
	hidden alias bug.
	(gcc_cv_as_ix86_quad): Check for .quad directive.
	* configure: Regenerate.
