Last message today. It seems that I succeded in switching all "invsqrt" functins to a new "gmx_invsqrt". Just 57 in the 12 files below:

With this, and with the configure flag "--disable-x86-64-sse", The compilation yelded only warnings. I reproduce they below. Should I be worried about any of them? The ones involving FFTs, and the ones about variables being used before declaration do not look too nice to me:

Unfortunatelly, as said in the last message, the code still complains when I try to compile it without the "--disable-x86-64-sse" flag in the configure script. Reallt strange is that I don't see why it complains in one case and not in the other, but the "configure" fails when tries to use libtool:
*************************************************************************************************************************************
/bin/sh ../../../../libtool --mode=compile /usr/bin/gcc -O3

Googling this error, I found it related to the changes in the compiler, but I could not get a way to fix it for gromacs. Did anyone crossed with this error before, in other context maybe? Any idea on how to fix it?
Anyway, thanks a lot to everybody for all in advance. If it was not your help, it would not be possible to get this far already! :) Almost there now, it seems! :)
Thank you all in advance again.
