Warnings about Boost (warning: The practice of declaring the Bind placeholders (_1, _2, ...) in the global namespace is deprecated)

[julien2412]

Hello,

On pc Debian x86-64 with master sources updated today + make clean && make
(since Boost has been upgraded), I noticed these kinds of warnings:

Debian clang version 11.0.0-5+b1
GNU ld (GNU Binutils for Debian) 2.35.1

It doesn't prevent LO from building but thought it could be interesting to
pinpoint.
