The error above appears on a freshly installed cygwin, on an older Windows
(VM) there is no such error.
On the new cygwin installation:
W10dev:~: ls -l /usr/bin/rsync
-rwxr-xr-x 1 admin None 2673952 Sep 6 10:27 /usr/bin/rsync
On the old (last year?) cygwin installation:
W10dev:~/WHOME: ls -l /usr/bin/rsync
-rwxr-xr-x 1 admin None 1842817 Jan 29 2016 /usr/bin/rsync
==> different rsync versions!

Strange... why doesn't my ldd list these additional libs?
Perhaps because they are not found?!
On UNIX ldd shows a "not found" error in such a case.

W10dev:~: apt-cyg find lz4
(...)
Searching for installable packages matching lz4:
liblz4-devel
liblz4_1
lz4
lz4-debuginfo
mingw64-i686-lz4
mingw64-x86_64-lz4
Is it liblz4_1 ?
(yes - see below!)

W10dev:/usr/local/bin: cp -av /cygdrive/z/tmp/rsync.exe .
'/cygdrive/z/tmp/rsync.exe' -> './rsync.exe'
W10dev:/usr/local/bin: type -a rsync
rsync is /usr/local/bin/rsync
rsync is /usr/bin/rsync
W10dev:/usr/local/bin: /usr/local/bin/rsync --version

W10dev:/usr/local/bin:
Tatatataaaaaaaaa! :-)
AND:
W10dev:~: apt-cyg install liblz4_1
(...)
Package liblz4_1 installed
W10dev:~: find /usr | grep lz4
/usr/bin/cyglz4-1.dll
W10dev:~: /usr/bin/rsync --version
rsync version 3.2.4dev protocol version 31
And now ldd shows:

cygz.dll => /usr/bin/cygz.dll (0x3fdaa0000)
Ok, this means: in the current cygwin distribution the rsync package is
broken?!
Where can I report this bug? Shall I at least?
