Yes, I kept gcc-4.6 to help resolving it.

Unfortunately it starts a full rebuild with plain make after compiling some files with gcc-4.6 - detects CC change? -- Meelis Roos (mr...@linux.ee) -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
