There is no such thing as LINE_MAX in C. LINE_MAX is a POSIX macro and
is specifically about the maximum line limits that POSIX utilities
support. Questions about POSIX belong elsewhere. Note that many several
implementations which otherwise try to be POSIX, for example GNU C, pay
no attention to that family of macros and that even though defined have
no useful information. And, again, it has no meaning at in C itself,
and has never been part of C, and is, obviously, 'deprecated'. That
which never was is not deprecated.
