* cppspec.c: Insert -no-gcc into command line unless -gcc was
given by user. * gcc.c (default_compilers): Define __GNUC__ and __GNUC_MINOR__ only if -no-gcc was not given. * objc/lang-specs.h: Likewise. * cpp.texi: Document -x and -std options; explain that -lang is no longer supported. Minor related corrections. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@26990 138bc75d-0d04-0410-961f-82ee72b054a4
