* localtime.cc (increment_overflow): Mark as non-inline to prevent compiler

from complaining about the very thing we're trying to test.
* ntea.cc (read_ea): Reorganize to avoid a new compiler warning/error.
* sched.cc (sched_rr_get_interval): Ditto.
* select.cc (peek_serial): Ditto.
* libc/rexec.cc (ruserpass): Ditto.
* posix_ipc.cc (ipc_names): Make static to avoid a compiler warning
(and it's the right thing to do anyway).
