I already had the link, it's something else.
pdb2gmx core dumps.
I just did it all over again, make clean, make, make install,
and it compiles no problem, but if I try pdb2gmx for example
it still core dumps.

The only non standard thing
was changing fmax for gmx_fmax as Erik suggested in
xutils.c

this is when you run grompp on the water example

      -load string         Releative load capacity of each node on a
parallel
                            machine. Be sure to use quotes around the
string,
                            which should contain a number for each node
    -maxwarn    int     10  Number of warnings after which input processing
                            stops
-[no]check14   bool     no  Remove 1-4 interactions without Van der Waals

Back Off! I just backed up mdout.mdp to ./#mdout.mdp.1#

Saludos a la gente de la Plata.

Claudio,
in my own cygwin installation the cpp preprocesor is located in /bin/cpp
rather than /lib/cpp
create a link in /lib/ pointing to /bin/cpp so usual mdp files will run ok.
cd /bin
ln /lib/cpp.exe
Saludos
