Looks very odd to me. The 10.0.023 version of ifort (x86_64) works fine
for me, as did many earlier versions.

Why are you making the above changes? The compiler probably won't hurt (it
won't help either), but changing cpp to fpp could lead to funny behavior -- it
would certainly be untested behavior, since amber developers would certainly
be testing the stock install.
