Subject: 	* fhandler.h (class fhandler_dev_raw): Delete current_position
 and 	eof_detected status flag.  Delete is_eom and is_eof methods. 	Move
 drive_size, bytes_per_sector, eom_detected status flag, as well 	as the
 methods read_file, write_file, raw_read and raw_write to ... 	(class
 fhandler_dev_floppy): ... here. Remove is_eom and is_eof 	methods.  Add
 dup method. 	* fhandler_floppy.cc (IS_EOM): New macro. 
 (fhandler_dev_floppy::is_eom): Remove. 	(fhandler_dev_floppy::is_eof):
 Remove. 	(fhandler_dev_floppy::fhandler_dev_floppy): Initialize status
 flags. 	(fhandler_dev_floppy::get_drive_info): Only call EX functions
 on 	systems supporting them and stop suffering strange delays. 
 (fhandler_dev_floppy::read_file): Move here, drop setting 
 current_position. 	(fhandler_dev_floppy::write_file): Move here, drop
 setting 	current_position. 	(fhandler_dev_floppy::open): Rearrange
 comment. 	(fhandler_dev_floppy::dup): New method. 
 (fhandler_dev_floppy::get_current_position): New inline method.  Use 
 instead of former current_position were appropriate. 
 (fhandler_dev_floppy::raw_read): Move here.  Drop EOF handling. 
 (fhandler_dev_floppy::raw_write): Move here.  Drop EOF handling. 
 (fhandler_dev_floppy::lseek): Remove useless conditions.  Convert 
 sector_aligned_offset to LARGE_INTEGER to improve SetFilePointer call. 
 (fhandler_dev_floppy::ioctl): Move blocksize check in RDSETBLK case 	to
 here. 	* fhandler_raw.cc (fhandler_dev_raw::is_eom): Remove. 
 (fhandler_dev_raw::is_eof): Remove. 	(fhandler_dev_raw::write_file):
 Remove. 	(fhandler_dev_raw::read_file): Remove. 
 (fhandler_dev_raw::raw_read): Remove. 	(fhandler_dev_raw::raw_write): Remove.
 	(fhandler_dev_raw::dup): Drop copying removed members. 
 (fhandler_dev_raw::ioctl): Drop blocksize testing. 	* wincap.h: Implement
 has_disk_ex_ioctls throughout. 	* wincap.cc: Ditto. 
 (wincap_vista): Preliminary wincaps for Windows Vista/Longhorn. 
 (wincapc::init): Add Vista/Longhorn handling.
