When IF_DESKTOP is not defined, chown and chgrp only takes option -R -h,
However the usage output of chgrp is wrong:
$ ./busybox.nosuid chown
Usage: chown [-Rh]... USER[:[GRP]] FILE...
$ ./busybox.nosuid chgrp
Usage: chgrp [-RhLHP]... GROUP FILE...
$ ./busybox.nosuid chgrp -H group dummy
chgrp: invalid option -- 'H'
Usage: chgrp [-RhLHP]... GROUP FILE...
The chgrp is now a wrapper of chown, so the recognized options shall be the same.
This is introduced by 34425389e0
I would expect the correct behavior shall be the same as chown.
So suggest the below patch, the behavior shall be:
$ ./busybox.nosuid chgrp
Usage: chgrp [-Rh]... GROUP FILE...

Review of real-world results of the above shows that with small
initial offsets, freq correction can be allowed to kick in sooner,
whereas with large (~0.8s) offsets, we still start freq correction
a bit too soon.
Let's rebalance this a bit.

Under some circumstances, a DNS reply might contain no resource records,
e.g. when a valid domain is queried that does not have records of the
requested type.
Example with nslookup from BIND dnsutils:
$ nslookup -q=SRV example.org
Server: 10.11.12.13
Address: 10.11.12.13#53
Non-authoritative answer:
*** Can't find example.org: No answer
Currently the busybox nslookup applet simply prints nothing after the
"Non-authoritative answer:" line in the same situation.
This change modifies nslookup to either print "Parse error" or "No answer"
diagnostics, depending on the parse_reply() return value.

When crond is built with FEATURE_CROND_SPECIAL_TIMES enabled, it creates
a file called 'crond.reboot' at CONFIG_PID_FILE_PATH, but if
FEATURE_PIDFILE is disabled, this will be an empty string and the file
will be created in the root directory, which is undesirable.
This commit makes PID_FILE_PATH depend on FEATURE_CROND_SPECIAL_TIMES as
well as FEATURE_PIDFILE so that you get sensible behaviour in crond when
FEATURE_PIDFILE is switched off.

Some 32-bit architectures no longer have the 32-bit time_t syscalls.
Instead they have suffixed syscalls that returns a 64-bit time_t. If
the architecture doesn't have the non-suffixed syscall and is using a
64-bit time_t let's use the suffixed syscall instead.
This fixes build issues when building for RISC-V 32-bit with 5.1+ kernel
headers.
If an architecture only supports the suffixed syscalls, but is still
using a 32-bit time_t report a compilation error. This avoids us have to
deal with converting between 64-bit and 32-bit values. There are
currently no architectures where this is the case.
