#     include/linux/compiler*.h: make compiler-*.h mutually exclusive
#     
#     Commit cafa0010cd51 ("Raise the minimum required gcc version to 4.6")
#     recently exposed a brittle part of the build for supporting non-gcc
#     compilers.
#     
#     Both Clang and ICC define __GNUC__, __GNUC_MINOR__, and
#     __GNUC_PATCHLEVEL__ for quick compatibility with code bases that haven't
#     added compiler specific checks for __clang__ or __INTEL_COMPILER.
#     
#     This is brittle, as they happened to get compatibility by posing as a
#     certain version of GCC.  This broke when upgrading the minimal version
#     of GCC required to build the kernel, to a version above what ICC and
#     Clang claim to be.
#     
#     Rather than always including compiler-gcc.h then undefining or
#     redefining macros in compiler-intel.h or compiler-clang.h, let's
#     separate out the compiler specific macro definitions into mutually
#     exclusive headers, do more proper compiler detection, and keep shared
#     definitions in compiler_types.h.
#
