OK. Do you know what implications there will be for Windows users such as
myself? 

I assume that the amr libraries are the "AMR Codec Libraries for
GNU-Linux" at:
http://www.penguin.cz/~utx/amr

My first attempt to compile them failed. libamrnb.a is created, with a
warning that undefined symbols are not allowed in Win32 shared libraries.
No DLL is created. It did not say which symbols were undefined. However,
I got link errors (undefined Decoder_Interface_init,
Decoder_Interface_Decode, and Decoder_Interface_exit) when it tried to
link amrnb-decoder.exe.

I don't want to try any harder until AMR is working in MPlayer again, but
I just want to point out to the MPlayer (and/or ffmpeg) developers that
it seems that this change will break AMR support on Windows.

I will contact the AMR library developers for help with building on
Windows.
