LOGNAME_MAX is not part of the standard.
As Solaris removed "utmp" and "wtmp" a long time ago, I would guess that
it can be seen as historical entry that may stay at it's current value
as long as the standard name LOGIN_NAME_MAX is OK.
I'm not proposing it stays at its current value though. The proposal is
that it be increased.
I don't see anywhere on limits.h(3HEAD) that says we won't change the
value of LOGNAME_MAX it is the name that would be the Committed
interface not the value of it.
LOGNAME_MAX is listed in the "Other Invariant Values" section. They way
I understand this is that it won't vary between compile time and run
time on this operating system, not that it won't ever change between
releases.
Code compiled on Solaris 10 or earlier or existing builds of OpenSolaris
won't magically be broken they will behave the same way the always do.
Code compiled on future releases/builds isn't guaranteed to work on
older releases/builds anyway.
