If no @option{--enable-checking} option is specified the stage1
compiler will be built with @samp{yes} checking enabled, otherwise
the stage1 checking flags are the same as specified by
@option{--enable-checking}. To build the stage1 compiler with
different checking options use @option{--enable-stage1-checking}.
The list of checking options is the same as for @option{--enable-checking}.
If your system is too slow or too small to bootstrap a released compiler
with checking for stage1 enabled, you can use @samp{--disable-stage1-checking}
to disable checking for the stage1 compiler.
