According to the documentation, I need to use gcc 4.2 for VFP support. I use the suggested flags
-mfpu=vfp -mfloat-abi=softvfp 
and get the following error:
invalid floating point abi: -mfloat-abi=softvfp

any suggestions?

here is full compiler output:

It should read -mfloat-abi=softfp. I'll get the typo fixed.
