@item --disable-bootstrap
For a native build, the default configuration is to perform
a 3-stage bootstrap of the compiler when @samp{make} is invoked,
testing that GCC can compile itself correctly. If you want to disable
this process, you can configure with @option{--disable-bootstrap}.
@item --enable-bootstrap
In special cases, you may want to perform a 3-stage build
even if the target and host triplets are different.
This could happen when the host can run code compiled for
the target (e.g.@: host is i686-linux, target is i486-linux).
Starting from GCC 4.2, to do this you have to configure explicitly
with @option{--enable-bootstrap}.

@section Building a native compiler
For a native build, the command @samp{make} will trigger a 3-stage

This will build the entire GCC system and ensure that it compiles
itself correctly. It can be disabled with the @option{--disable-bootstrap}
parameter to @samp{configure}, but bootstrapping is suggested because
the compiler will be tested more completely and could also have
better performance.
The bootstrapping process will complete the following steps:
