Comment (by eipi):
It seems the most convenient solution for elevating a process using win32
would be to run that process through ShellExecuteEx. The trick is that a
new verb can be used in the SHELLEXECUTEINFO struct (field "lpVerb"),
setting it with value "runas". If started in this way, the process will
display the UAC dialog for authorization instead of failing. So for Cabal,
it seems the copy and dir creation could be handled by spawning a new
process using the win32 API as descibed above.
