Why did you need to add this?  This is only required if some ANSI or
Posix function calls fchown.  I don't think this is the case.

                ^^^^^^^^^^^^
This should have been __FSEXT_fchown ;-).

I thought you wanted to check that the handle is valid, no?  As
written, this will succeed for any value passed as FD, even if it is
65535 or -1.  Is that a good idea?
