[mpich-discuss] Problem with MPICH 3.0 rc1 compilation on RHEL 5

[Dave Goodell]

This is because you have selected a bare "--enable-strict" option to configure, which defaults to c89.  I'll see if there's a more pleasant way around this, but in the meantime is it acceptable for you to pass "--enable-strict=c99" instead?

The problem occurs because your compiler still responds to the "long long" type but disables the "LLONG_MAX" constant when asked for c89 mode.
