Hi,

Please consider building capnproto with -std=c++20 enabled. I tried to
use the C++20 coroutine support in my application and while it compiled
successfully, it failed to link because the necessary coroutine
functions don't exist in the Debian package.

Since GCC 16 enables C++20 and is now the default in Debian, a simple
rebuild with no other changes might be enough to fix this (although
explicitly enabling C++20 might be better?)

Thanks,
James
