Problem recompiling version 3.1

[Gerson H Cohen]

I am having a problem recompiling Xplor 3.1 on an Irix 5.3 system.
The link fails with the following:

 Linking: f77 -o xplor.exe *.o -s /usr/programs/xplor/xplor_3.1/sgi/fft/libfft.a
  -mips2
ld:
Unresolved:
mp_numthreads_
mp_my_threadnum_

There are no other apparent errors in the installation attempt.  The only
reference I can find to mp_numthreads_ is in sgitime; I find no reference to
mp_my_threadnum_.  Can anyone supply me with a set of com files that work
under this configuration.
