cppspec.c: Insert -no-gcc into command line unless -gcc was given by user.
* 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.
