C++ is not supported by GCC based C30 for dsPIC. Please refer to the
following thread.

dsPICs do have the features you need (DIP and 5V I/O) except C++.

AVRs have good GCC support and has DIP and 5V I/O. There are some
limited C++ support as well.

MSP430s have good GCC support (I think C++ is not really supported).

By the way, IAR seems to support embedded C++ for
dsPIC/AVR/MSP430/ARM but it is not free. There are limitted kickstart
edition though.

There are single 5V supply ARMs available from companies like ST
(STR7 ARM7) but no DIP.

Personally I think 3V operation is not a problem. DIP package can be a
problem but there are prototype boards available just as you mentioned.

In a world, dsPIC/AVR/MSP430/ARM are some of the options.
