Hmm, I thought bootstrap used -Werror, but I just noticed some build 
warnings from this change.  Fixed thus.
commit 9bf1c74e01512f43f764c9a4d437f9d999b74117

    	* attribs.c (lookup_attribute_spec): Take const_tree.
    	* tree.h: Adjust.
    	* c-family/c-common.c (attribute_takes_identifier_p): Add missing const.
