>From the Solaris cc (not ld) man page:

#     -mt  Passes D_REENTRANT to preprocessor.  Appends  -lthread.
#          If  you are doing your own multithread coding, you must
#          use this option in the  compile  and  link  steps.   To
#          obtain  faster  execution,  this option requires a mul-
#          tiprocessor system. On a single-processor  system,  the
#          resulting executable usually runs more slowly with this
#          option.

So I don't know that it /ensures/ that the argument order is "-lpthread
-lc" but it does just append -lpthread, and the normal compiler driver
just appends -lc to /that/.

The native Solaris ld doesn't have an -mt option AFAICT.


H.J., when you said

did you mean "should accept -mt on Solaris" or did you mean "should use
[the effects of] -mt by default"?  I'm assuming you meant the former.
