As did the rest of the world, I guess.. ;)

You do recall correctly :)
In fact, you're right: the only thing is I was patching ls, but come to 
think of it, the cygdrive magic dir (and any other magic dir) should 
just come through a stat() call correctly, and opendir() and readdir() 
should handle it correctly.

As it's better to grab a bug by the guts than just pull its antenna's 
off, I'm back to the bug hunt (got the hat, the net and everything :)

I just have a question about the stat() implementation: there seem to be 
a lot of them (different ones for different systems, ofcourse). I should 
probably take the one from go32? (looks very DJGPP-ish to me, but that 
could just be me).

Same question (and same assumed probable answer) for opendir() and 
readdir()?

The implementations I'm referring to here are in newlib/libc/sys/go32
The reason I think it might be these is because they seem to be DOS 
implementations, and the cygwin directory (meaning 
newlib/libc/sys/cygwin) doesn't contain any implementations.
Building and examining the makefiles takes a rather long time, and as 
you - or other people on the list - probably know where these functions 
live by heart, it's a lot easier to just ask..

Greetz & Thanx!
