* TODO
* - Special processing of 32-bit executables is not supported, so this
* version cannot patch 32-bit .exe and .dll files. See pa19.c for details.
* - Implement interleaved decoding when PATCH_OPTION_INTERLEAVE_FILES was
* used or the old file exceeds the lzxd window size.
* - APPLY_OPTION_FAIL_IF_CLOSE is ignored. Normalization of 32-bit PE files
* is required for checking this.
* - GetFilePatchSignature* and NormalizeFileForPatchSignature require a
* solution to the above 32-bit exe problem.
