Thanks both for your answer and your willingness to look into this.

STC:
1)  Have Tor Browser for Windows up and running.
2)  Start dirmngr:
   $ mkdir ${HOME}/try
   $ dirmngr --homedir ${HOME}/try -vvv --debug-all --server --use-tor
   -> KS_GET -- 0x6C6ACD6417B3ACB1

Basically, dirmngr should be able to connect to TBB for Windows like it 
does on linux and retreave the key.

Let me know if more informations are needed.
I  came to this list  because the issue seems to come from Cygwin, 
according  to the discussion at the first URL in this e-mail.
