Re: NTLM compiler compatibility problem ?

My opinion is that one should not overuse bitfields, especially not for
a such low count usage as stateful helpers..

  sateful_helper_reserve_t reserved;

Having the type as an enum is of great benefit when debugging, and
generates much better code than to have it as a bitfield.
