The .exe suffix is added if all of the below is true:

- The file is renamed via the rename(2) function.
- The name does not only change by case on a caseinsensitive mount.
- The file is a binary checked with the Win32 function GetBinaryType,
  and the returned type is SCS_32BIT_BINARY or SCS_64BIT_BINARY.
- The source filename has none of the following suffixes:
    .com
    .dll
    .exe
    .scr
    .sys
- The destination filename has none of the aforementioned suffixes.
