75 <para>For a native build, GCC defaults to performing a 3-stage
76 "bootstrap" of the compiler. This means that GCC is compiled a total
77 of 3 times - it is compiled once, the first stage compiler is used
78 to build itself again, and the second stage compiler builds itself
79 once more. The second and third passes are then compared, verifying
80 that GCC is able to reproduce itself successfully. However, there is
81 no need for this with the CLFS build process so we disable it here.</para>
