> The second strange thing is "unsigned long <name>:1". I'm not sure but as far as I can remember the right way to define several-bits field is "int <name>:1". But I might be mistaken.

A bitfield of size 1 should not be signed, as there's no space for a sign bit.
Usually, you want all bitfields to be unsigned anyway.
