compiling amber 7 with Intel Fortran Compiler 6.0 (fwd)

We have compiled amber 7 using the following flags for
high optimization (L3) in the MACHINE file:

For P4:

-O2 -tpp7 -align -Zp8 -axW -ipo -ipo_obj -unroll

For Athlon:

-O3 -tpp6 -align -Zp8 -axiM -ipo -ipo_obj -unroll

I just stripped these from an unrelated makefile that
I came across and they seem to work fine. I haven't
fooled around with these much, but we haven't had any
noticable problems, and the test outputs looked good.
I should note that we have only been using sander,
and antechamber a little, but the other tests looked OK.

PS: this is with version 6.0 of ifc.

Subject: compiling amber 7 with Intel Fortran Compiler 6.0

        Dear all,
        I have been trying to compile amber 7 using IFC 6.0. I tried to
modify Machine.ifc file in order to get advantage from the SSE2, that
gives faster binaries. To do so, I included the flags "-tpp7 -xW" into the
MACHINEFLAGS variable, but when the compilation starts I got a message
stating that the new flags are not recognized.
        Could you please, tell me how modify properly the machine file or
send me a copy of any machine file that works with those flags.
        Thank you in advance.
