Do it using (__CHAR_BIT__ * __SIZEOF_LONG__), simpler, works everywhere, reduces the complexity by ditching CONFIG_64BIT, that was being synthesized from yet another set of defines, which proved fragile, breaking the build on linux-next for no obvious reasons. Committer Note: Except on: gcc version 4.1.2 20080704 (Red Hat 4.1.2-55) Fallback to __WORDSIZE in that case...
