  Yes, we know, we heard you the first time.  And the second time.  And the
third time.  You come across as rather demanding.  If you find the customer
service round here isn't snappy enough to meet your expectations, you're
welcome to a *full* refund....

  Just use plain 'cpp', which is most likely what you should have been using
all along.  The C preprocessor functionality was originally a separate
subprogram from the compiler, so 'cpp0' was called to do the preprocessing
and the result was passed to 'cc1', the actual compiler.  Both the 'gcc' and
'cpp' executables are simple driver programs that handle invoking the
various stages, passing output from one to the next, and separating out the
various command line flags that each stage understands.  The preprocessor
functionality is now builtin to 'cc1', so there is no need for a standalone
'cpp0'; the equivalent function could be achieved by using 'cc1 -E'.
However, you should really just use 'gcc -E' or 'cpp -E' and allow the
driver to take care of getting things right for you; it was never right to
be invoking 'cpp0' anymore than it would be to invoke 'cc1' directly as part
of a compilation.  The drivers are wrappers that are there to isolate and
protect you from these sort of under-the-bonnet changes; if you make an
end-run around that protection, this is what you get.

  Just not your day, is it?
