Sorry, poor wording choice. To be honest, I don't even know
if managed mounts still have those limitations since I don't
use them, although that was my understanding at the time.

My approach was to use underlying NT services that bypass
normal Windows naming restrictions, allowing more or less
arbitrary Unicode strings as file names. It had path length
limitations, but they were no worse than what Windows has
already. It was my understanding that Cygwin managed mounts
did this by escaping such characters into multi-character
sequences, which of course would cause you to run into the
Windows limits sooner. There are other ways to accomplish
this, so the mechanism may have changed for all I know.

(I don't necessarily expect that there will be any interest
in my solution, but I thought that I should mention it just
in case. As I said, there are other ways to deal with this
without imposing path length limitations, and I don't even
know how much of a concern such limits are in general.)
