	* gcc.c (default_compilers): Add -no-integrated-cpp flag to invoke
	  an external cpp during compilation.
	(option_map): Likewise.
	* cp/lang-specs.h (default_compilers): Similarly.
	* objc/lang-specs.h (default_compilers): Similarly.
	* doc/invoke.texi: Document -no-integrated-cpp flag.

+Performs a compilation in two passes: preprocessing and compiling.  This
+option allows a user supplied "cc1", "cc1plus", or "cc1obj" via the
+@option{-B} option. The user supplied compilation step can then add in
+an additional preprocessing step after normal preprocessing but before
+compiling. The default is to use the integrated cpp (internal cpp)

+The semantics of this option will change if "cc1", "cc1plus", and
