[Ffmpeg-devel] Latest SVN failing to configure

[Aaron Williams]

I'm a bit sorry about the tone of my last email.  The problem in configure 
seems to be caused by the addition of -Wl,--as-needed.  This seems to 
somehow make the order of the libraries important, or else it breaks 
something in the linker.  In my testing, if I remove this, I no longer 
need to add -lm after -ldts.
