Indeed, but as pointed out by DaveK2:

I can confirm that.

Indeed.

Ah, I didn't know that, is that documented somewhere ?

Just the same.

Indeed.

Well, xbrlapi is not useful by itself alone with X11, it is only useful
with other applications, so that building a separate package just for it
to pull the X11 dependency looked to me quite abusive, but I can still
do that.

That would make programming less easy.  Brltty can communicate with
other (potentially non-cygwin) applications with tcp/ip (remotely) or
local pipes (locally, more efficiently).  For keeping compatibility with
other applications for local pipes, windows pipes are used. Mixing
cygwin sockets and windows local pipes is not particularly fun, so
that's why we end up just using windows socket and
WaitForMultipleObjects() in a separate thread.

About the linux-utils, it was needed in previous brltty revisions, but
not any more, so I'll drop it.
