This patch set is a dependency of the generic red-black tree patch set, which I have now split up into three smaller sets.
The major aim of this patch set is to cleanup compiler-gcc*.h and improve the manageability of of compiler features at various versions (when they are broken, etc.), and to cleanup & add some needed features to bug.h.
compiler-gcc*.h o Introduce GCC_VERSION - (e.g., gcc 4.7.1 becomes 40701) o Reorder all features based upon the version introduced (readability) o Change all version checks to use GCC_VERSION o Remove redundant __linktime_error
bug.h o Improve BUILD_BUG_ON(expr) - Will now generate a compile-time error and in gcc-4.4+, also emits an error message containing the expression that failed. o Add BUILD_BUG_ON_MSG(expr, msg) - Like BUILD_BUG_ON, except that you can specify the error message that is emitted (again, gcc-4.4+). o Add BUILD_BUG_ON_INTERNAL(expr, fn, msg) - contains a generic implementation of BUILG_BUG_ON{_MSG}. o Finally, the implementations of BUILD_BUG{,_ON,_ON_MSG} is consolidated, eliminating duplicate code.
