Fixed by ensuring unsigned long ctx->timeout does not overflow the signed
long timeout.tv_sec.

Moved setting of "now" to earlier in the function.

This was true; octdigits was used in no lib/dns/**/* files.

These three were all in atob_tobuffer, where the value of stroul was being
assigned to an isc_int32_t, which is typedef'd from int and possibly smaller
than long (definitely on the IRIX machine). The variables in question were
changed from isc_int32_t to long.

The values in question were already being checked to be within the range of
a short, so where the warnings were occuring they were just cast to int.

by using UNUSED() on this stack variable. I didn't take it out altogether
because this function is not yet finished, but someone was starting to
do some work on it and I didn't want to undo that.
"./rdata/generic/nxt_30.c", line 66: warning(1042): operand types are

"./rdata/generic/loc_29.c", line ??: remark(1506): implicit conversion from

by making sure that the range was suitable for an int and casting to
int in each case. (This appeared to be more desirable than changing
all of the variables in question to longs.)

By chaning them to ==, because (a) we don't allow side-effects in REQUIRE()

was desired and not an assignment.

Note that the first is in timer_cleanup, a function returning void in a context
that can't do anything with something other than void (as an isc_taskaction_t).
It calls isc_timer_reset, which could conceivably return ISC_R_NOMEMORY or
ISC_R_UNEXPECTED. For now the call has been cast to void, but someone
who knows the code better should have a look and see whether something more
intelligent could be done with an error (and, if not, remove my XXX and
make sure the comment is clear as to why ignoring the return is the
best that can be done).
