    Enabled by using the --enable-lto configuration option.
    May give a slight performance improvement in some cases, but it can
    also reduce performance in other cases (largely compiler-dependant)
    so don't enable it by default. It also makes compilation (and linking
    in particular) a fair bit slower.
    Note that some older versions of GNU binutils will incorrectly warn
    about "memset used with constant zero length parameter" when linking
    using LTO. This is due to a bug in binutils and can safely be ignored.
