[COMMIT] Fix compiler warnings in ada-lang.c

[Mark Kettenis <kettenis at gnu dot org>]

This patch fixes a compiler warning in ada-lang.c:lim_warning().  GCC
was complaining about not being able to check the format string in the
warning() call.  Solved by turning lim_warning into a varargs
function.  I don't think there is another way.

Committed as obvious.

	* ada-lang.c (lim_warning): Re-implement as a varargs function.
	(decode_packed_array_type, value_subscript_packed)
	(ada_evaluate_subexp, to_fixed_range_type): Remove redundant
	argument in call to lim_warning.
