I want to be able to refer to an external function by two
different names without the overhead of duplicated code.

The following seems to work on all compilers I've tried

      REAL FUNCTION NAME1(arg list)
      REAL NAME2
      ENTRY NAME2(same arg list as name1)
      .
      .
      .
      NAME1 = result
      END

i.e. nowhere do I assign a value to NAME2. Is this legal Fortran 77?
I've had a good look through the standard but can't find a ruling
either way. Only section 18.2.2 looks sort of hopeful.

Can anyone give me chapter and verse either way please?
