Necessary to bootstrap GCC, although versions of GCC prior
to 3.4 also allow bootstrapping with a traditional (K&R) C compiler.
to 4.8 also allow bootstrapping with a ISO C89 compiler and versions
of GCC prior to 3.4 also allow bootstrapping with a traditional
(K&R) C compiler.
To build all languages in a cross-compiler or other configuration where
3-stage bootstrap is not performed, you need to start with an existing
GCC binary (version 2.95 or later) because source code for language
GCC binary (version 3.4 or later) because source code for language
frontends other than C might use GCC extensions.
