I've run into this problem before.  std(in,out) cannout be assigned to
FILE * variables other than in main.  (Yes, I consider this a major bug.
Unfortunatly, prime doesn't always agree with me.)

Same problem, differnt eror message.  I havn't found a GOOD (no mod to
program source) workaround.

Huh what?  Always use -newfortran or -32ix unless you have code
specificly writen for the old meathod of calling "fortran" (other
language) procedures.  (If you do have such code, I recomend fixing
it.) -32ix is a big win in some cases.

Ps: for those of you interested, note the info-prime mailing list address
below.
