Don't want to report this as a bug if it's not...but.

Dowload 4-Oct-2007 version of buildroot. Choose ARM
processor, choose 'soft-float' in make menuconfig.

I have never gotten soft-float to work with BuildRoot.
Is this is a bug or my error ? If there is anything
else to post to determine the problem, let me know.

Build platform is i386 Ubuntu 7.04

Much appreciated
