added the recommended assembly code to _start.S as follows:

    /* Enable VFP */
    ldr     r0, =0x40000000
    fmxr    fpexc, r0

I get the following error:

I'm thinking that I need to set -mcpu=???, but haven't figured out what to set this to. Or, do I need to do something 
else?

Thanks,
Todd
