Yes, the binaries that I download were straight from codesourcery.

It works now. Linking with ld versus gcc seemed to be the problem. Note, in 
case someone else is having a similar problem, I also needed to add the 
-nostartfiles flag to remove _mainCRTstart, _start, __bss_end__, etc. 
namespace conflict errors. Took me a few minutes to figure that one out.

Thank you for the help.

Cheers,
Chris
