+ Please note the warning under @option{-fgcse} about

++NOTE: In Gentoo, @option{-D_FORTIFY_SOURCE=2} is set by default, and is
++activated when @option{-O} is set to 2 or higher.  This enables additional
++compile-time and run-time checks for several libc functions.  To disable,
++specify either @option{-U_FORTIFY_SOURCE} or @option{-D_FORTIFY_SOURCE=0}.
