Thanks Tom. In fact, yesterday I was writing without remembering my past
analyses of this type of issue, with system header warnings not suppressed:
TREE_NO_WARNING is *not* generically uses for that. Everything boils down to
DECL_IN_SYSTEM_HEADER on the decl instead.
Now, the warning at issue is the *only* one directly emitted from pt.c and the
following draft works for me.
What do you think, Mark?
Otherwise, elsewhere we are dealing with these issues by going through the
saved_in_system_header dance...
Index: pt.c
