* harbour/src/rtl/fscopy.c
* added runtime error for HB_FCOPY() bad param types only
* made a function HB_FCOPY() a pure file system function
does not dependent on _SET_DEFAULT setting
; File open mode is not altered a avoid any influence on OS/2
behaviour if source and destination files are the same (see
ChangeLog entry at 2009-11-24 16:57). I guess, hb_fsExpOpen()
still can be changed to hb_fsOpen() with FO_EXCLUSIVE,
FO_CREAT, and FO_TRUNC but I'm unable to test it, so, I leave
current code.
