[mpich-discuss] --enable-strictmpi not respected

[Kenneth Raffenetti]

Hi Levi,

Yes, this looks like a bug with how we include directories in the 
Automake SUBDIRS variable. I've created a ticket to track the issue and 
investigate other occurrences.

However, the fact that it's searching for these symbols at all seems to indicate that the --enable-strictmpi option isn't being respected since the MPIX_* functions are nonstandard.
