	STDCXX-481
	* sunpro.config (CCMAJOR, CCMINOR): New variables for the major
	and minor version of the compiler.
	(DEPENDFLAGS.cpp, DEPENDFLAGS.S): New variables for compiler options
	to generate makefile dependencies from C++ and assembly source files,
	respectively.
	(wide_flags): Set to -m64 for Sun C++ 5.9 and beyond, and for 5.8
	and prior to -xarch=v9 on SPARC and to -xarch=amd64 on AMD64.
	(narrow_flags): Set to -m32 for Sun C++ 5.9 and beyond, and for C++
	5.8 and prior to -xarch=v8 on SPARC, -xarch=386 on AMD64, and to
	-xarch=generic otherwise.
	* makefile.rules (makedep): Used DEPENDFLAGS$(depsuffix) to set
	compiler options to generate makefile dependencies.
	(depsuffix): Defined a target-specific variable to the suffix of
	the first prerequisite of the %.d pattern rule used to generate
	makefile dependencies.
	(DEPENDFLAGS, DEPENDFLAGS.cpp, DEPENDFLAGS.S, DEPENDFLAGS.s): Set
	appropriately when not defined or empty, and guarded .d: %.cpp and
	%.d: %$(AS_EXT) pattern rules.
	(GNUmakefile.cfg): Commented out make variables whose names do not
	form valid shell variable names (i.e., those containing periods)
	from the gernerated vars.sh file.
	* GNUmakefile (DEPENDFLAGS, DEPENDFLAGS.cpp, DEPENDFLAGS$(AS_EXT):
	Wrote definitions to the generated makefile.in.
