/* NOTE: In DOS/DJGPP under WinNT4 hb_fsSeek( fhnd, offset < 0, FS_SET ) will
set the file pointer to the passed negative value and the subsequent
hb_fsWrite() call will fail. In CA-Cl*pper, _fsSeek() will fail,
the pointer will not be moved and thus the _fsWrite() call will
successfully write the buffer to the current file position. [vszakats]
