Comment:
You mean the correct code is this, right?:
{{{
c_len <- #{peek ZNotice_t, z_message_len} c_note
c_msg <- #{peek ZNotice_t, z_message} c_note
message <- B.packCStringLen (c_msg, fromIntegral (c_len :: CInt))
}}}
I don't think there's anything we can do. You can `peek` anything that is
`Storable`, and while that does have a `sizeof` method I don't see a
reasonable way for `hsc2hs` to call it with the right type.
