[Coin-ipopt] mpich2 issues

[Scott Turnberg]

Hi,
I've been trying to compile the development version of ipopt with 
mumps.  I am using MPICH2.  I've been getting the errors shown below.  I 
finally have been able to get this to compile by changing lines 12..15 
of IpMumpsSolverInterface.cpp

from

extern "C"
{
#include "mpi.h"
}

to

#include "mpi.h"
