Hello,
     I just installed Gromacs on my windows machine under cygwin, and
everything seemed to go fine with the installation and whatnot.  Initially,
when I tried to run a simulation, I obtained the error that Gromacs found the
number of coordinates in my .top file to be 0, because it could not find the
cpp.  From the mailing list archives, I gathered that Gromacs was checking
for cpp in /lib/cpp whereas in cygwin the cpp is in /bin/cpp.  So, as in the
post, I created a link in /lib pointing to /bin/cpp.  I ran a simulation, and
everything went fine.  Now, I am trying to run another simulation, and I am
running into the same problem as before.  When I execute grompp, I get this
error:
Back Off! I just backed up md_shear_run.mdp to ./#md_shear_run.mdp.2#
checking input for internal consistency...
...ling /lib/cpp
: No such file or directory
cpp exit code: 32512

replace /lib/cpp with /bin/cpp (with or without .exe) in the mdp file
