New option --enable-c-cpplib to configure script.
- Allow --with-cpu on configure command to specify a default CPU.
+ You can use --with-cpu on the configure command to specify the default
+ CPU that GCC should generate code for.
The -specs=file switch allows you to override default specs used in
invoking programs like cc1, as, etc.
