I think this should be fixable now that mapped locations have gone in.
The key is to have c_lex_with_flags return a value for in_system_header
which comes from the token's "original" location, not the macro expansion
location. I am not sure if this will do the right thing with token pasting.
And, it probably will not work for something like:
/* system */
#define F(x) x
/* user */
F(somethingToCauseAWarning)
It isn't clear to me whether we would want the warning here or not.
