We are using Ethernet on that platform (ST9), but indirectly via a Rabbit 
coprocessor. In principle it could support Ethernet directly but we decided 
to change to another processor (M32C) rather than continue to fight with the 
ST9's bank switching.

I would guess they were supported when C++ support was implemented, but I 
don't know when that happened. It is possible that the first implementations 
may have limited C++ comments to C++ source files, until someone suggested 
they also be supported in plain C.
