[TCLCORE] Windows Bug: directory junctions: noe step further

[Harald O. <har...@el...>]

There are two related windows tcl bugs:
- tclbug 3587096: startup error message when exe in folder with junction
with limited rights
- tclbug 3092089: file normalize vanishes path component after junction

Junctions are something like softlinks in unix.

One year ago, Mark Garvey proposed a patch to change requested file
access and I have tested this today.

The patch solves both issues but introduces many "access denied"
failures in the tcl test suite.

I want to invite a wizard (Jan, Jos, Alexandre) to look after the issue.
It seams close to the solution.

Thank you,
Harald
