I noticed this was still broken, so I wrote a patch for it, and checked 
it in.  The solution that seems right to me is the same one that Per 
suggested, namely, changing c_common_post_options to set errorcount when 
the input file is missing.

I tested this patch with an x86 linux bootstrap and make check.  There 
were no regressions.
