I realised there are docs provided only for gcc/g++, objc/objc++, gccint, 
gfortran, libgccjit, libgomp, libquadmath, but nothing for libstdc++, not even 
info or man pages.

Is there any chance we could possibly get libstdc++.info* or man pages included 
with the build, or as (a) separate -doc package(s), and possibly other libraries 
or components where info or man pages are available, and may not currently be 
built or installed?

I struggled to find any Cygwin or online docs mentioning libstdc++, until a 
poster linked:

     https://gcc.gnu.org/onlinedocs/libstdc++/manual/using_dual_abi.html,

One upstream refuses to support distros that do not support C++20 compilers!

Given that cygwin/-devel is built with the old ABI, is there any point in trying 
to build libraries/packages that *require* the new ABI features in C++20?

I am asking to adopt dependent orphaned packages, just so I *can* rebuild them 
with the new ABI, so is trying this exercise going to be futile?
