Hi!

I used to program C and inline assembler with DJGPP under DOS in the nineties.

Now I have a hobby project that would target DOS (yes, seriously), and I would like to take the opportunity to get beyond the basics of C++ and actually learn the language proper. So I'll try to implement this program in as elegant C++ code as possible. (The program will be of a moderate size and I have written similar programs before in C)

Having spent some time reading up on C++, it seems that C++ has evolved a lot in recent years, and modern C++ is quite different from the dog-turned-octopus I remember frowning upon.

So, my questions:

* "Which C++" can I realistically expect to use with DJGPP? To what extent are features from C++11 supported? C++03?

* Google led me to a DJGPP version 2.04-beta. Is this usable?

* Which GCC version is the latest I can use with DJGPP? (without having to do any porting myself)

* Can I expect the same performance from C++/DJGPP over C/DJGPP, when targeting something like a 20MHz 80386 with 2mb RAM?

(The the development will _not_ be done on the 386, even with RHIDE and all...)
