[Coin-discuss] Compile BCP 1.0.0 with mpich

[Laszlo Ladanyi]

Oops.. my fault... In the past only one of BCP_message_single.cpp and
BCP_message_mpi.cpp was compiled and linked into the code. Therefore the
BCP_process destructor was defined in both of these sources (and in ..._pvm as
well). Basically, I just didn't want to create a separate source file for 4
lines of code...

However, now all available interfaces are linked into the library and the user
can choose. So it's an error to define the destructor everywhere. Since the
single interface is always available, the destructor should be defined there
and nowhere else. Just remove it from _mpi.cpp and you should be OK.
