* alpha-tdep.c (init_extra_frame_info): Remove kludge for gcc,

	gcc has to be compatible with the native tools.
	* alpha-tdep.c (alpha_push_arguments):  Rename NUM_ARG_REGS to
	ALPHA_NUM_ARG_REGS and move its definition to tm-alpha.h.
	* config/alpha/tm-alpha.h (FRAME_ARGS_ADDRESS):  Change it to the
	way the native tools define it, update comment.

-        gcc-2.4.5 builds frames for the alpha in a peculiar way.
-        It uses $fp as a frame register (which seems to be identical to $sp
-        in all procedures that do not use alloca).
-        It has the arguments and the locals above the frame register, if
-        there are few arguments then the locals are above the arguments,
-        otherwise the arguments are above the local.
-        Frame offsets for arguments and locals are relative to $fp and always
-        positive.
-        If we want to stay compatible with the native cc compiler we have
-        to set localoff to frameoffset so that FRAME_ARGS_ADDRESS and
-        FRAME_LOCALS_ADDRESS point to the right place in the frame.
-        Please note that the setting of localoff in the compiler won't work
-        as localoff is only 8 bits wide (which is enough for cc as it needs
-        at most number_of_arg_regs * 8 == 48).  */
