Why does gcc say "unknown demangling style `dlang'" ? Do I need 
GDC for demangling to work ?

I'm not familiar with that flag maybe you have to register ddmangle with it? But failing all else you can pipe the output through ddmangle.

Check your version of binutils with `ld --version`. It looks like it was added in v2.25: http://forum.dlang.org/post/rvoqllpimfskvlabprot forum.dlang.org I tested with 2.29.1 and it worked fine for me. Mike

Yes, thanks Mike. I have 2.24 installed. Now I have to figure out 
how I can upgrade binutils without a distro upgrade. :)
