GHCI is unable to load 'network' package on Windows. The versions:

$ ghci --version
The Glorious Glasgow Haskell Compilation System, version 7.4.2

$ ghc-pkg list network
c:/mnt/data1/ghc32b\lib\package.conf.d:
    network-2.3.0.14

The test code:

import Network

main = withSocketsDo $ do listenOn (PortNumber 3333) -- >>= accept

The failure:

The load trace log ('+RTS -Dl'):

The symbol to be resolved:

$ nm network-2.3.0.14/ghc-7.4.2/HSnetwork-2.3.0.14.o |grep WSACleanup
         U __imp__WSACleanup@0

The actual symbol in the foreign library:

The test snippet only works when compiled by ghc (so the resulting binary is produced by ld.bfd).
