[mpich-devel] LLONG_MAX undeclared in status_set_elements_x.c ?

[Dave Goodell]

Howard, what configure options are you using?  We've seen a problem like this when "--enable-strict=c89" is passed, since the features.h header deliberately avoids defining LLONG_MAX when in C89 mode.  I haven't had the time to come up with a fix for this yet.
