I thought that was the case.  I did it about 3 weeks ago.

Well that's good and bad.  I use ifc to compile a molecular
mechanics suite called AMBER (not freely available).  A F90 or
later compiler is required, so g77 won't suffice.  The AMBER
mailing list has documented that only certain versions of ifc v8
will (1) compile the key AMBER program, and (2) generate code
which can reproduce known good trajectories (generated by earlier
AMBER code compiled with many different compilers, not just g77).
These new differences from one minor version to another increase
the work necessary to work around the Intel compilers
"peculiarities".  On the up side, WHEN THEY WORK, the Intel
compilers produce easily demonstrably faster code.

That's very good to hear.
