A THandle is more than a file descriptor alone.
Since the LCL is VCL compatible and thus MS biassed, there are more
THandles than filedescriptors alone. To keep code compatible and portable,
I need a 64 bit THandle on 64 bit platforms. (on win64 a handle is also
64bit).
Or would you suggest to use HANDLE for a 64bit handle and THandle for
32bit ?
