Hi Simon,

This is available on other architectures, and nds32 will start to break without it as code starts to use error numbers more.

Thanks for your patch.
I've also noticed that NDS32 currently has compiling error because of -fstack-usage option has been enabled by default. However, the gcc-4.6 compiler for nds32 is still under developing. I've told compiler team to speed up developing work on gcc-4.6 and later. If there were fail on compiling test of nds32 architecture, please ignore it. Sorry for the inconvenince.
I don't see that one at present, but I do get these with gcc 4.4.4:

If you don't support a gcc option it should be possible to disable it in U-Boot for your toolchain as a temporary workaround. It would be good to get a pointer to your toolchain at some point.
