to sources. This logic was trying to use non-free
usage requirements that are not supported, and can
potentially result in inconsistent builds.

- Add _static in library name as necessary
- Define _STLP_USE_DYNAMIC_LIB depending

Patch from David Deakins.
Addresses #1177.

silly mistakes like using a negative time for the select
timeout.
Also added the setrlimit call back in since the
named_condition_test occassionally consumes multiple cpus
worth of time. That is, when I ran this test -j4, I found
the named_condition test consuming 4 cpus worth of time so
after 300 seconds of elapsed time when the test timed out,
it had consumed almost 1200 seconds worth of cpu. While the
test is killed after the elapsed time expired, setting a hard
cpu limit ensures it's killed after consuming either -lx seconds
worth of cpu or -lx seconds of elapsed time.
[SVN r39613]
Added an optimization to the -lx unix timeout code. I
compute the amount of time the select call should sleep
until the "oldest" process times out. This ensures that
all processes that timeout will be killed within one
second of their expiration.

Fixed problems with threading, pic code, missing math
library, etc. to get mipspro toolset working better.
Updated pgi toolset to fix various problems with the
link line.

The intel based darwin system was killing subprocesses
okay but for some reason, ppc systems were not. This
change fixes the timeout code so subprocesses are
properly killed on ppc darwin systems.

sub-processes after bjam forks a new process (for example, after
g++ is forked by bjam, g++ then forks sub-processes like cc1plus).
The timeout code would kill the g++ process, but might not kill
the subprocesses spawned by g++.
I fixed this problem by making the bjam fork'ed process (g++) a
session leader by calling setsid() before calling exec. The setsid
call, in essence, gives all child processes a parent process id
(ppid) of the g++ process id. This guarantees that killing g++
will kill all child processes spawned by g++ as well.
One last comment on the maximum process time before a process is actually
killed. The worst case process elapsed time is 2x seconds if -lx is
given. The reason is that a process might be one second away from being
killed and, if there's no other signal activity, the select function will
wait x seconds before timing out and killing any active processes. So
if you say -lx and monitor a build known to have lengthy processes, you
may see a process with up to 2x seconds of time before it is killed.

when a process has timed out and been killed.
Because timed out processes now emit a diagnostic, I
had to update option_l.jam so we wouldn't break test.sh
when it runs.
Minor cleanup to execunix.c to remove unneeded code
and to set the process exit status as returned from
waitpid. The exit status is used to identify timed
out processes so we can emit a diagnostic to the user.

AIX. Apparently AIX doesn't permit a forked process to
reference (set) memory in the parent's address space. No
other system seems to object to this practice but it taught
me a lesson!
The fix was to move the call to get the child process start
time directly before calling vfork. This isn't really fair
to the forked process as we start counting time against the
child process that we haven't even forked (we count the
vfork/exec call overhead against the child process).
Tested Rene's test.sh script on Sun, Linux, AIX, and Sgi.

emit each referenced template in the object file
where referenced and then rely on the linker to
remove duplicates.
Added some missing macros to sgi_mipspro.hpp.

the timeout implementation. Also removed unused variables
as diagnosed by the Sgi (mipspro) compiler.
Fixed const-correctness error in operations.hpp that
Sgi complained about.
There's no strerror_r function on Irix 6.5 so I replaced
it with a strerror call.
With these changes, I can now build process jam log and
start running Sgi tests.

to times, one to kill). Now all expired processes
are killed in one place. If the select command
times out, I set each processes start_time to zero
to ensure it is picked up as an expired process.
[SVN r39361]
terminate expired processes. This patch basically
causes the select function to return after -l seconds.
This gives me a shot at killing processes still
running.
[SVN r39358]
make_pair with std:: to library_status.cpp.
Added missing headers to make1.c and missing prototypes
to builtin.h
Modified execunix.c to add support for terminating
processes that consume too much cpu or that hang and
fail to consume cpu at all. This in support of the
bjam -lx option.
