Subject: Re: [OMPI devel] openmpi-1.2.6 and pvfs-2.7.0+ Support
From: Jeff Squyres (jsquyres_at_[hidden])

Just to clarify -- are you saying that the function signature for
PVFS_sys_create() has changed over time and that in some versions it
takes 6 parameters, and in other versions it takes 7 parameters? (I
know nothing about PVFS)

Thanks!
