75 - new ECB_MEMORXY_FENCE_RELAXED memory fence.
76 - use acquire/eelease memory barriers on sun workshop pro, not read/write.
77 - rely on c++ compiler barriers to do the right thing in gcc/clang.
78 - change release memory fence to memory barrier on ia32/ia64.
66 - apply ctz/ld patch for msc by Zsbán Ambrus. 79 - apply ctz/ld patch for msc by Zsbán Ambrus.
80 - ECB_PTRSIZE erroneously was 8 on most 32bit systems (
81 found by Zsbán Ambrus).
82 - improved compiletime detection of endianness, also, allow
83 runtime detection to indicate other-than-big/little endianness.
84 - no memory barrier neded on arm < 6.
