Возникло желание внедрить во вражескую сущность немного православных генов! использовать Unix утилиты в Windows.
С учетом не широкого выбора остановился на cygwin.
По ходу дела был найден отличный скрипт apt-cyg – хорошая такая замена дебиановскому APT-у.
Вот только со времен последнего коммита прошло 3 года и репозиторий cygwin похоже сменил свою структуру.
Если раньше (судя по коду утилиты) была только ветка x86, то теперь присутствует еще и x86_64.
А потому корректно работать скрипт отказался.

Письмо автору написал, но для нуждающихся выкладываю diff (для ревизии r18):

--- apt-cyg	2013-08-13 00:14:33.474995644 +0700
+++ apt-cyg2	2013-08-13 00:40:08.292016974 +0700

   then
     touch setup.ini
     mv setup.ini setup.ini-save
-    wget -N $mirror/setup.bz2
+    if [ `uname -m` = "x86_64" ]
+    then
+      arch="x86_64"
+    else
+      arch="x86"
+    fi
+    wget -N $mirror/$arch/setup.bz2
     if test -e setup.bz2 && test $? -eq 0
     then
       bunzip2 setup.bz2

Для совсем нуждающихся весь скрипт с исправлением под катом.

UPD: Тут форк. Обновляется.
