--- Comment #3 from Martin Sebor <msebor at gcc dot gnu.org> ---
If the only thing the new option is meant to control is -Wattributes warnings I
tend to agree that adding an optional argument to -Wattributes= would be a
natural enhancement. (Similar to -Wnormalized= or -Wsuggest-attribute= except
with a free-form string as an argument).  I would expect the existing
diagnostic pragmas to work with it too:

#pragma GCC ignored "-Wattributes=vendor::attr1"
