For reading the version of a Windows executable on a Linux one you'd 
need to copy what the resource API on Windows does plus parsing the 
executable image.
For reading the version of a Linux executable on Windows you'd need to 
check how FPC implements this version information and parse the 
executable image accordingly.

For Windows definitely correct, for Linux I don't know, but seems legit...
