[AMBER] Workaround for gfortran-4.1.2?

Hello all,

I am trying to compile against gcc-4.1.2 which includes the buggy

I'm trying to compile with -O2 instead of the default -O3. Does anyone
know of any other things to try, or specific compiler flags that allow
a work-around of the buggy section in fortran?

I am aware that 4.3.2 and 4.4.x are out, but my system is old ( Centos
4.3 ) which doesn't have RPMS for those compilers. Further, if I
upgrade the compiler ( more specifically the libraries ) I need to go
back and recompile && regression test all the other MD suites in use.
It's a non-trivial number so I really don't want to do that. We
expect that we will be getting new Hardware soon which will allow for
an upgrade of OS and such, then I can roll the old hardware to the new
system. But that is later. For now, upgrade is not an option.
