[mpich-discuss] MPICH2's predefined reduce operation can not support quadruple precision

[Jayesh Krishna]

Hi,
 I am currently trying to see if I can recreate your problem (Cygwin+MPICH2 compilation error).
 The ticket pointed out in the discussion (https://trac.mcs.anl.gov/projects/mpich2/ticket/1028), may or may not be related to your problem (Atleast the error messages are different).
 Did you get the error message with MPICH2 on windows (Installed using the MSI installer on windows) or cygwin (Installed using configure/make/make install) ? Which version of MPICH2 are you using (on windows)?

Regards,
Jayesh

I don't know much about Windows/Cygwin. I'll let our windows expert take 
this over.
