I always thought that -O2 could be duplicated by using a (very long) set of individual command line options. Regardless, the point of this patch is to record which options were enabled, via whatever route, in the binaries. This can be useful to users, or distributors, who want to check that, for example, a specific security option was enabled, or that a particular a particular optimization was run. Cheers Nick
