It's up to you. I'll repeat what I said before. Amber 6 was written before
there was an Intel compiler, and it looks like it is not compatible. Amber
7 (the current release) works fine with ifc. So my best suggestion is to
either get the current release of Amber, or to use one of the compilers
that is supported with Amber 6.

You could try splitting gibb.f into smaller pieces -- I think that will make
ifc happy. But you would be putting in a lot of work for very little gain:
g77-compiled code is not much slower than ifc-compiled code. If you are
truly concerned about performance, you should upgrade to the new version of
Amber anyway, since it is faster for most jobs than is Amber 6.

(All of this assumes you are planning to use gibbs in the first place; if
you aren't, the above problems may be irrelevant to you.)

....hope this helps....dac
