C++ PATCH to cp/decl.c: Timing name lookup

[Andrew Pinski]

Your patch broke the bootstrap on an i696-pc-linux-gnu because it 
produces a warning during the second stage:
/home/gates/pinskia/src/gnu/gcc/src/gcc/cp/decl.c: In function 
`define_label':
/home/gates/pinskia/src/gnu/gcc/src/gcc/cp/decl.c:5006: warning: return 
makes pointer from integer without a cast

The problem is you `return ( timevar_pop (TV_NAME_LOOKUP), 0)' which is 
wrong if the return type is a pointer.

Here is patch which should fix it:
(note this was copied from a terminal which means the tabs might be 
been turned into spaces).

	* decl.c: (define_label): Fix warning for return 0 instead of NULL.
