Yup. Just the same effect that we get with the integrated
preprocessor.

I wasn't sure it was necessary. I only tried to limit the effects of
my change. I don't see how it would be possible for us to take a line
change while processing a macro.

Only if they have line breaks in their macro invocations.

I don't have any remaining problems in bootstrapping GCC with a mix of
separate and integrate preprocessing after this patch. Debugging
information is now identical regardless of which preprocessing
mechanism is used, but I don't know how much coverage a GCC bootstrap
represents in this regard. I know I had lots of differences before
the patch, but I haven't examined the complete set of sources of
differences.
