Comment (by cjones051073):

 The command line tools package does not install to /usr/include. Instead
 it installs SDKs to /Library/Developer/CommandLineTools

 I see no difference in the behaviour or content of gcc10, compared to
 gcc9.

 {{{
 Oberon ~/Downloads > port contents gcc9 | grep wchar
   /opt/local/include/gcc9/c++/cwchar
   /opt/local/include/gcc9/c++/tr1/cwchar
   /opt/local/include/gcc9/c++/tr1/wchar.h
 Oberon ~/Downloads > port contents gcc10 | grep wchar
   /opt/local/include/gcc10/c++/cwchar
   /opt/local/include/gcc10/c++/tr1/cwchar
   /opt/local/include/gcc10/c++/tr1/wchar.h
 Oberon ~/Downloads > port contents libgcc10 | grep wchar
   /opt/local/include/gcc/c++/cwchar
   /opt/local/include/gcc/c++/tr1/cwchar
   /opt/local/include/gcc/c++/tr1/wchar.h
 }}}

 Please test build the example application I posted above, using the -H
 option, and compare to the logs I attached above.
