src/gnu/dist/gcc/gcc/doc: cpp.1 cpp.info cppenv.texi
As discussed on firstname.lastname@example.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.
