That's strange, I've built my own APR and not had this issue or needed
to do set those option (although that might explain the weirdness I'm
seeing on my Mac as that's using 1.4.2 built by MacPorts), I can't
remember if I built 1.4.2 on Fedora or not but I'll give it a go when I
have a chance and see if I run into similar issues.

Let me know if you find anything else out about this.

Regards
Tim
