Well, it looks like my new version of git properly handles the

This patch set is a dependency of the generic red-black tree patch set, which
I have now split up into three smaller sets and is based off of linux-next.
The major aim of this patch set is to cleanup compiler-gcc*.h and improve

are broken, etc.), add some needed features to bug.h and clean that up as

o Reorder all features based upon the version introduced (readability).
o Change all version checks to use GCC_VERSION.
o Remove redundant __linktime_error macro.
o Introduce compiletime_assert() macro.
o Improve BUILD_BUG_ON(expr) - now generates compile-time error post-gcc-4.4
