Rolling back to gcc-g++ 9.3.0 did not help.
I did find that entry point string in cmake.exe (all the lowercase 'L's
I typed in that are actually capital i's. My font makes no distinction)
and I was able to locate a matching string in
/lib/gcc/x86_64-pc-cygwin/9.3.0/libstdc++.a, but not in libstdc++.dll.a.
Running strings on the /usr/bin/cygstdc++-6.dll showed the same
information. Maybe I need to roll back further!
