Peter Anvin <hpa@xxxxxxxxxxxxxxx> CommitDate: Wed, 25 Feb 2009 17:28:00 -0800 compiler-gcc4: conditionalize #error on __KERNEL__ Impact: Fix for exported headers We only want to error out on specific gcc versions if we are actually building the kernel, so conditionalize the #if...#error on __KERNEL__.
