This then is an argument for reverting Nathan's patch, as usability-wise
if the compiler is able to say "you need to do this", it can also itself
do "this", especially if "this" is "running gcc again with -C".  It would
make me angry by a large amount if I ever would see this message.  In
Nathans view it was a regression because it was'nt behaving the way it was
before, but I consider the old behaviour broken (I was disturbed multiple
times by cc1 not accepting comments), so it's a negative regression, or a
bug fix.  (Well, it all depends on definition of "preprocessed"; does it
include comments or not; if it doesn't we can make "gcc -c a.i" mean:
"accept preprocessed source with optional comments").  So, I vote for
reverting.


Ciao,
