New Revision: 170550

URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=170550
Log:
Add an error when pre-parsing a header that does not have a double
inclusion guard.

We do this by adding function cpp_main_missing_guard that returns
the name of the main source file when it does not have a guard, and
checking that condition before writing the PPH file.
