No. Under obsolete versions of POSIX, if {NO_TRUNC} is nonzero, an
application should assume that pathname components longer than
{NAME_MAX} are not truncated, but instead result in the [ENAMETOOLONG]
error. Under the current version of POSIX, [ENAMETOOLONG] is
mandatory for all systems; this was an obsolete option to allow for
the behavior of the V7 filesystem, which has been phased out.
