    Fix format-security GCC warning
    
    In Fedora land, format-security GCC warnings are treated as errors
    so the build would fail like this:
    
    In file included from /usr/include/pgsql/server/postgres.h:48:0,
                     from rdkit.h:40,
                     from mol_op.c:33:
    mol_op.c:339:19: error: format not a string literal and no format arguments [-Werror=format-security]
         elog(WARNING, t);
                       ^
