No.  That's why they should not be used.  Use the POSIX-standard *_MAX
variables instead.

Hopefully this one will be in the next POSIX.  The current draft
spells it `255'.  I have proposed {HOST_NAME_MAX} which would
definitively include the terminating '\0'.

Use {NAME_MAX}.

>   intro(2) suggests that this does include space for a NUL - seems right.

Use {PATH_MAX}.
