While it was said before gdbserver should stay in C I did not see it long-term
maintainable - due to the code sharing goals. While I wanted to simplify the
talk excluding gdbserver first we can talk even about C++ization of gdbserver.
Which specific platforms do you talk about which is UNIX compatible (=FSF
gdbserver compatible, not just an embedded stub) and cannot run C++ programs?
(*) Please give examples of viable platforms with future development.
(*) The smallest device I know about is SIM card - and it runs Java (Card) VM,
therefore more heavy environment than C++.

The mail lists all the code parts which cannot be C++ized. I do not find that
too interesting. I find interesting code parts which can be C++ized - such as
anything about symbols/types outside of gdbserver.

Not just that one, std::string vs. cleanups vs. exceptions are even more
wanted (by me); just static typing (probably) cannot be done without C++,
the other parts are still being fixed up without C++.
