--- Comment #1 from Ian Lance Taylor <ian at airs dot com> --- There is nothing in the cgo tool which would cause this error. When the command runs "go", which go tool is actually running? The difference may be that on platforms other than powerpc-linux-gnu it is running the go tool from the gc compiler, but on powerpc-linux-gnu it is running the go tool from the gccgo compiler. This could potentially happen because the gc compiler does not support 32-bit powerpc.
