- Global io_copy_attrs (const file_pair *pair)
- ACL and EA support
- File sha256.c
- Crypto++ has x86 ASM optimizations. They use SSE so if they are imported to liblzma, SSE instructions need to be used conditionally to keep the code working on older boxes.
- File tuklib_integer.h
- PowerPC and possibly some other architectures support byte swapping load and store instructions. This file doesn't take advantage of those instructions.
