From: Andi Kleen <ak@xxxxxxxxxxxxxxx> gcc recently switched to a new version number scheme, where every version gets a new major version number. The current version is 5.x, the next 6.x, etc. The gcc git repository trunk branch just switched to report 6.x for the next major release. This breaks the way Linux selects compiler-gccX.h based on the major version. Every new version would require adding a new compiler-gccX.h file, which wouldn't really scale. Let's assume that future gccs are fairly compatible (they are unlikely to break anything Linux is relying on). So we can just keep using compiler-gcc5.h, and select any specific differences with #if.
