Again, the shipping Win32 version of cpp.exe is perfectly working with
Gromacs 64-bit on a opetron m/c which is a x86-64 box.
But I guess it (the above cpp.exe) may not work on pure x64 m/c as its not a
valid x64 application.
Is there a x64 port of cpp.exe is available ?
Can we use other (native windows) c preprocessor ?
Sorry, if I'm making silly queries.
Cpp.exe is called by grompp to preprocess the topology.
