* hppa-tdep.c: Remove all uses of use_unwind and `set use_unwind'

	command.  Now we use unwind info by default if we can find it.

	* config/sparc: Move VARIABLES_INSIDE_BLOCK and SUN_FIXED_LBRAC_BUG
	to tm-sparc.h so they are shared between Solaris and SunOS4.
	* dbxread.c (process_one_symbol): Deal with SunOS4 acc N_STSYM and
	N_GSYM functions.
