[MPlayer-dev-eng] [PATCH] Detect extern_prefix correctly on OpenBSD

[Edd Barrett]

Hi,

I am going to try and get mplayer working out of the box on OpenBSD. Let's start
with this:

nm prints results differently on OpenBSD than on linux. We have been using this
following patch for a while in our ports tree. I hope I am correct to
patch the configure script directly. I see no GNU autotools inputs, so I
am assuming the script is written by hand.

Index: configure
