** Description changed:
- There are compilation errors when I try to include the <glibmm.h> header
under C++20.
+ There are compilation errors when I try to include the <glibmm.h> header
under C++20 and run default compiler, GCC 11.
This is reproducible in Ubuntu 21.10 (Impish Indri) or Ubuntu devel (Jammy
Jellyfish) but not in Ubuntu 21.04 (Impish Indri) or Debian unstable. And this
is effecting building of the telegram-desktop package.

+ [Test Plan]
+ Run the following two terminal commands in Bash:
+ 1. sudo apt-get satisfy libglibmm-2.4-dev 'build-essential | g++'
+ 2. g++ -x c++ -std=gnu++20 -include glibmm.h - <<< 'int main(){}' `pkg-config
--cflags --libs glibmm-2.4` -o /dev/null
+
+ [Where problems could occur]
+ The proposed patch only modifies C++ headers. It may affect only building
other packages from source or developer experience.
