FYI, C99 has been required since late 2012. Going through the commits there is 
no way Open MPI could possibly compile with —std=c89 or —std=gnu99. Older 
compilers require we add —std=c99 so we can not remove the configure check.


commit aebd1ea43237741bd29878604b742b14cc87d68b
Author: Nathan Hjelm <hje...@lanl.gov>
Date:   Wed Nov 14 04:52:39 2012 +0000

    Per discussion we will now require a C99 compiant compiler.
    
    This change will enable the use of C99 features in Open MPI; subobject 
naming, restricted pointers, etc.
    
    cmr:v1.7
    
    This commit was SVN r27604.
