It looks like there's still something not quite right because it's warning on
some instances but not others and I'm not certain why. Can you investigate?
================
Comment at: clang/test/Preprocessor/line-directive.c:33-34
# 42 "foo" 2 // expected-error {{invalid line marker flag '2': cannot pop
empty include stack}}
# 42 "foo" 1 3 // enter
# 42 "foo" 2 3 // exit
# 42 "foo" 2 3 4 // expected-error {{invalid line marker flag '2': cannot pop
empty include stack}}
----------------
Something is still not quite correct -- these should also be diagnosed as an
extension (it's the same feature just with flags).
================
Comment at: clang/test/Preprocessor/line-directive.c:61
# 192 "glomp.h" 3 // System header.
typedef int y; // ok
----------------
This should also be diagnosed.
