c-parse.in: save and restore warn_pointer_arith on __extension__ along with pedantic.
* c-parse.in: save and restore warn_pointer_arith on __extension__
along with pedantic.
(SAVE_WARN_FLAGS, RESTORE_WARN_FLAGS): Added.
Set the type of extension to itype rather than $<itype>1 kludge.
* extend.texi (Alternate Keywords): Adjust documentation.
* c-parse.c, c-parse.y, objc-parse.c, objc-parse.y: Rebuilt.
