The latter two links are coming up not found, as are the links to the C

use the Sun style or the krb5 style for GSSAPI code, I'm about to
discuss that in a meeting and will likely have more to say later.

Regarding bitfields: I was not suggesting using flag fields and bitwise
arithmetic over bitfields.  The previous code just used a pair of ints,
while the new code uses three 1-bit bitfields.  The idea is to sacrifice
a bit of heap space to give the compiler an easier job, not to try to
write better code than the compiler can.  Whether the flags are accessed
on performance-sensitive paths is irrelevant; the concern is code size,
not speed, so the question is how many times the flags are accessed in
the code, not how often at runtime.  Basically, I am questioning whether
this is premature optimization.
