My first guess would be that you have a 32 bit alignment problem.  FTN66 is
a 16 bit compiler and will align INTEGER*4 on 16 bit boundaries.  I assume
you are compiling with FTNXL on a 32 bit machine.  FTNXL is a 32 bit native
mode compiler that wants to align INTEGER*4 on 32 bit boundaries.  It will
complain if your EQUIVALENCE attempts to align on a 16 bit boundary.

You can override the default 32 bit boundary alignment by adding the
following compiler directive:

$HP3000_16 ALIGNMENT
