It seems quite apparent that the windows glob no longer
works right on patterns that begin with slash.
This install was built from snapshot file:
tcl-20040213.tar.gz

I can reproduce it, so I'll look into fixing it.

I have a fix for this, but in the same way that glob
'foo\\bar' gets converted to 'foo/bar' in the list of
results, it will convert your 'glob /p/airvid' to list
results as 'C:/p/airvid ...'.
Is that ok?

This will work for me in my present usage.
The fix which adds a drive component doesn't "feel" right to
me and I wonder if it will create incompatibility bugs upon
migration from 8.4 to 8.5. BTW, is this behavior covered in
the test cases?

Unfortunately, volumerelative paths are hardly tested in the
test suite (I assume you would have run the test suite
yourself before reporting this anyway?).
8.4 therefore has a number of problems with such paths --
some stuff works, some doesn't. In particular, vfs support
for volume relative paths is v. poor in 8.4 (but ok in 8.5).

I note that 'glob //Machine/Shared/*' also fails, and I'm
fixing that too.
