As there has been no other answer, I will point something out,
even though I am NOT an expert in this procedure.  m2c is a
compiler for the language Modula-2.  You are not using that (are
you?), but it seems to be invoked (by make) because of your
Fortran module file (jian.mod).  Fortran compilers in my
experience don't need to be told to look for x.mod when you have
specified x.obj.  Can you run this procedure without mentioning
the module file?

I hope this helps.
