Subject: ls -lt *.c doesn't sort files by time as I expected it would

I have ported the ls.c posted to this newsgroup to Intel's
iRMX286 operating system (the system I use at work). I did this
because the DIR command that is stock with iRMX is pretty shabby,
and doesn't have many nice features. I really wanted to be able
to list files sorted by time order. When I was testing it, I
discovered that if I did:
	ls -lt
it properly sorted all of the files in the current directory, but
if I tried:
	ls -lt *.c
it didn't sort by the time. Any easy fixes to ls.c? Does ls.c
have this same problem on minix (did I break something in my
port)?

(By the way, the port to the iRMX system involved calling unix
library emulation routines for readdir() stat(), file globbing
(expand *.c into many arguments) and time-related routines). At
least one hour was spent tracking down some mysterious compile
errors (cc286) that happened because the "entry" variable passed
to various functions is apparently an undocumented reserved word
to our compiler. I fixed the problem by globbally changing
"entry" to "p_entry". Unfortunately, in iRMX, all arguments
(argv[]) are received in upper case, so I still have to make some
other changes to make it work on this Intel development system
(ha ha Intel, if you can hear me).


On a side topic, are there any better public domain ls.c programs
available? Is the BSD ls.c public domain?
