I admit that my adding USER_LABEL_PREFIX was a cargo-cult fix (since before that, the alias was broken on OS X, I think?)
If you have a patch that fixes this correctly on all the relevant architectures (linux, os x i386, os x ppc) then I'm happy for Philip to apply it! I don't claim to have any actual knowledge here; this prefix stuff is a black art to me. craig -- ## List details at http://lists.exim.org/mailman/listinfo/pcre-dev
