When I tried to open any zip or jar archive in dired and view contents 
of any file
inside, Emacs just writes "caution: filename not matched: "<internal path>".
An investigation with Process Explorer Monitor has led me to believe 
that Emacs
launches the unzip executable with parameters -qq -c "<filename>"
"\"<internal path>\"", and the extra escaped quotes in the last 
parameter are
the source of the problem.

Replacing

"(if (equal (car archive-zip-extract) "unzip")
     (shell-quote-argument name)
       name)"

with "name"

in arc-mode.el and recompiling the file solved the problem.
