You should build it at least twice, using the first one to rebuild
itself. If you're not using an earlier version of GCC on the first pass,
or if you're using a much older version of GCC, you should build it _three_
times and with optimizations suppressed during the first build. Each new
version often has additional optimizations that are useful in the compiler
itself (you want compiles to run as quickly as possible don't you?) and the
executable file(s) for the compiler won't benefit from them unless they've
been built with the newer compiler...
GCC 2.3.* has some annoying new warnings (under -Wparentheses, which
is included as part of -Wall) that you may not like.
