Cygwin mount limited to 64 mounts, even for UNC paths?

[Martin Wege]

Hello,

Cygwin mount(1) is (per docs) limited to 64 mounts. Why was that
limitation chosen, and does it  apply even if I create bind mounts to
UNC paths (not DOS letters)? DOS letters might be restricted by the
ASCII A-Z, but UNC paths are unlimited.

Thanks,
Martin
