>         Environment: Ubuntu Precise, Ubuntu Oneiric, Debian Unstable
>            Reporter: James Page
>            Assignee: Trevor Robinson

> Recent releases of Ubuntu and Debian have switched to using --as-needed as default when linking binaries.
> As a result the AC_COMPUTE_NEEDED_DSO fails to find the required DSO names during execution of configure resulting in a build failure.
> Explicitly using "-Wl,--no-as-needed" in this macro when required resolves this issue.
> See http://wiki.debian.org/ToolChain/DSOLinking for a few more details
