gcc version 10.2.0 (Homebrew GCC 10.2.0) 
Target: x86_64-apple-darwin19

Lots of deprecated warnings for #pragma GCC diagnostic ignored "-Wdeprecated-copy", use of boost/bind.hpp and boost/detail/iterator.hpp. But otherwise OK.

Net: Apple's clang and g++ generated pretty similar warnings.  Clang-11 did not.
