f9f2fe447d Eliminate dos_getftime, dos_getfsize, and dos_getfattr_fd, because we can 
now get these properties directly from the SFT.

d7d201a53b This is the main change to eliminate far fnodes. 
SFT info is copied from and to the two near fnodes.
Some cleanups still follow.

affddaaf64 Handle dos_getfattr and dos_setfattr directly at the directory level, instead 
of opening the file, to avoid needing to claim SFTs in later changes.
Clarify and implement parts of the correct SHARE behaviour.

ba75006b67 Use explicit dir_write() instead of letting dir_close() do the writing.

d39420dc11 Add f_dirsector (sector containing dentry) and f_diridx (index within 
sector) fields to the fnode, to make fnodes more compatible with SFTs.

2092745236 Force near fnode use to use either fnode[0] or fnode[1] instead of the 
allocation scheme. This eliminates the checks done in inthndlr.c because
the f_count field is no longer checked.

d6ad12a3dc Add Linux cross-compile capability, using Open Watcom: 
* Flip \ to / where possible.
* Introduce $(DIRSEP) (/ or \) for use inside commands in makefiles
  where / won't work in DOS.
* Override various settings for Linux in owlinux.mak.
* Add quotes in exeflat.c to avoid shell expansion of $$$$$.
* Let "make all", "make clean", and "make clobber" do the job.

31bc1f6149 Added support for BUFFERSHIGH as alias to BUFFERS: No new code 
but useful for people who are used to writing HIGH everywhere.
Thanks to Christian Wallbaum the hint that config.txt had both.
Removed code which called int 16.1 in a loop before 16.0 - this
would only be useful if you invoke HLT before each int 16.1 ...

26f116a217 More secure FAT handling: Avoids risk of cross links for example if 
you reboot while files are open... Reported by Hardi Stengelin :-).

Always test *link_fat* result. New function is_free_cluster.  Extra
checks in *link_fat* (bad r/w offset, i/o, write) and *next_cluster*
(dangling chain: bad value in chain) with short messages (no msg for
bad chain start). Shorter "Bad DPB" (FAT size) msg.  More comments!

Update FS INFO on disk only when needed.  Check if chain EOF was at
expected place when extending.  Call *link_fat* before! *setdstart*
when a FAT chain grows.   [Q: Does 0 byte write always trunc? Why?]

0cc297cf2d The truename function must use the current working directory of 
the virtual / created-by-subst drive when it resolves relative
paths, even though truename returns the "real" drive and dir
of where your files actually are in the end. Using the current
directory of the "real" drive made truename give wrong results.

PS: If "subst e: d:\" says "physical path x:\ cannot be made",
then it refers to "making" a root dir. "subst e: d:\foo" works.

94085ce923 Changed copy() to use a two pass algorithm: Now SYS first calls 
copy to read kernel and command.com into RAM, then updates the
boot sector, then calls copy again to write kernel and command
from RAM to disk. This reduces disk changes a lot when you do
SYS A: B: on a PC which only has 1 diskette drive ("DJ style").
