simple FORTRAN code for GEMPAK that fails on 64-bit Linux machines

[David Ovens]

Gembuds,

I have this incredibly simple FORTAN code, test.f, that works fine on
32-bit Linux machines with any version of GEMPAK, but that fails
miserably on all of my 64-bit Linux machines with any version of
GEMPAK (I've tried 5.9.4 and 5.8.3ag3 specially built for 64-bit).  I
am curious if anyone out there can successfully run this on a 64-bit
Linux machine.  And, if you can, please share your
$NAWIPS/config/Makefile.linux.

Code test.f:
      program test
      call in_bdta(iret)
      u = 5
      v = 4
      spd = pr_sped(u,v)
      print *,'spd = ',spd
      stop
      end

Compile and run:
  ifort test.f $GEMLIB/gemlib.a -lg2c; a.out

Correct answer:
 spd =    6.403124    

64-bit Linux box answer:
 spd =  -1.0842022E-19


Cheers,

David
