[MPICH] Having Problems When Linking with Microsoft Visual C++ 6.0

[Calin Iaru]

Hi Sertaç,

you mentioned VC 6.0 as your application compiler. You should download 
the latest Platform SDK and use the compiler from there. The link errors 
below are generated due to the fact that the mpi library has been 
compiled with a more recent version of MS C compiler which has added the 
extra symbols. The Platform SDK can be found on 
www.msdn.com/PlatformSDK; you can integrate the Platform SDK supplied 
compiler with the IDE by using the msdev /useenv swich.

Best regards,
Calin
