Re: [ft-devel] LD version script

Just let me know if you want me to proceed.  I am not going to spend the time on this if the consensus (sans me) is that we don't need/want it.

I guess we don't need this.

I don't object, and it could be integrated into the `FT_EXPORT' macro,
AFAICS.  However, this doesn't give versioned symbols.  IIRC, Drepper
recommends to use both approaches: the `__visibility__' attribute
improves code generation of the compiler, and the map file provides
symbol versioning.
