[PATCH] Fix warnings from gcc 4.1.1

[Pavel Roskin <proski@gnu.org>]

From: Pavel Roskin <proski@gnu.org>

These warnings are reported for every file:
lib.h: In function 'add_symbol':
lib.h:171: warning: value computed is not used
lib.h: In function 'add_statement':
lib.h:176: warning: value computed is not used
lib.h: In function 'add_expression':
lib.h:181: warning: value computed is not used

That's the way new versions of gcc warn about values that are cast to a
type but not used.

The cast in add_ptr_list_tag() is not really needed.  Its return value
is used only in one place (add_pseudo) where it's converted to (void *)
anyway.
