Fix problem with I/O pipeline messages where the version of the format
for a I/O pipeline message could depend on the "use the latest format" flag from
the file after it was initially created.
Tested on:
FreeBSD/32 6.2 (duty)
FreeBSD/64 6.2 (liberty)
Linux/32 2.6 (kagiso)
Mac OS X/32 10.4.10 (amazon)
Solaris/32 2.10 (linew)
