Dunno about widnows, but posix and unix claim to have a PATH_MAX.
Unix file system code doesn't usually check (after all it would have
to know the max depth at any point - otherwise you could rename a
directory and exceed the limit way down the file tree).

It is the sort of limit that is rather painful - you either allocate
a massive (on stack) buffer most of which is never needed (and
traditiobally fail to check for overflow) or dynamically allocate a
buffer that is big enough and don't have a limit at all.
