My preferred design would be:
1. Add a gettimeofday() equivalent to libkrb5support, prototyped in
k5-platform.h. Best if the API looks like gettimeofday() to callers
(#defined to k5_gettimeofday on platforms which don't have native
gettimeofday) but if that causes problems it's not a hard requirement.
2. Use that function in prng_fortuna.c and c_ustime.c.
The mutex and massaging code in c_ustime.c can stay where they are.
