drand48.3: Remove crufty text about SVID 3 marking drand48() obsolete
...
See http://bugs.debian.org/758293
drand48() is in current POSIX. It's unclear why SVID 3 would
have marked it obsolete, but that's crufty information that
only serves to pointlessly worry people.

clock.3: The switch to the use of clock_gettime() was to improve *accuracy*
...
Quoting Vincent Lefevre:
In glibc 2.17 and earlier, clock() was implemented on top of
times(2). For improved precision, since glibc 2.18, it is
^^^^^^^^^^^^^^^^^^
implemented on top of clock_gettime(2) (using the
CLOCK_PROCESS_CPUTIME_ID clock).
This looks strange. The user doesn't seek improved precision, but
improved accuracy: if one gets more digits but the value itself is
less accurate (i.e. the error against the ideal value is larger),
this is bad. Perhaps changing "precision" to "accuracy" would be
correct (I assume that the real goal of the change was not just
improved precision, but more importantly the resulting improved
accuracy). I've reported a bug about the glibc documentation:

flock.2: Don't mention "classical BSD" in discussion of fcntl()/flock interaction
...
The noninteraction of flock(2) and fcntl(2) locks does
not seem to be classical BSD semantics (at least, checking
the 4.4BSD sources suggest that the lock types do interact,
although there have been other systems also where fcntl()
and flock() locks do not interact). So, fix the text
discussing "classical BSD" lock semantics.
