>Description:
The following code :

extern "C" int snprintf();

when compiled with g++ from CVS head, gives :

a.c:1: error: nonnull argument with out-of-range operand number (arg 1, operand
   3)

Joseph Myers : 

"It appears that handle_nonnull_attribute fails to check for
ATTR_FLAG_BUILT_IN in its flags argument.  This is used for the built-in
format attributes specifically to avoid that problem."
