[Pw_forum] Two binaries for serial and parallel use needed

Dear linux experts

I have newly set up our computer cluster with new mpich2 (1.07) 
and ifort. 
In the last cluster the binary pw.x (compiled with mpich2 1.04) could be 
executed directly or with mpiexec for serial or parallel use, 
respectively.
Now, this is not possible anymore, I always have to start an smpd 
and run pw.x with mpiexec, even for serial usage.
It is a bit uncomfortable, so if anyone knows a switch for the compiler, 
or could comment I would greatly appreciate it.

Cheers
Marcel
