--- Comment #30 from Bernd Schmidt <bernds at gcc dot gnu.org> ---
I'm just using CPP_W_NONE in the patch I'm testing and that seems to work.
Regarding the error message, here's what we'll get:
69650.c:4:55: warning: file "fish" left but not entered
# 9 "fish" 2 /* { dg-error "left but not entered" } */
The problem is that the file we'd be leaving is 69650.c, as shown by the
warning's location. "fish" AFAICT is the file we'd be switching to.
