>As discussed on tech-toolchain@netbsd.org, make cpp refuse to attempt to
>parse a #include'd file which does not pass S_ISREG() if the environment variable
>CPP_RESTRICTED is set.
>
>This is primarily intended for use by programs such as calendar(1) which
>use cpp to parse untrusted user files -- without this change (and the corresponding
>change to calendar(1)), any user can cause a denial-of-service for the daily
>calendar -a run by #include'ing a named pipe.

>Many thanks to christos@netbsd for his help in polishing this.
