* 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.
