I don't know about the speed, but any decent build environment can easily
automate this process. It's not much different from the earlier C compilers
(create assembler code, run the assembler over it to create relocatable
object code, link that into a hex file or whatever representation of the
binary). 

In the simplest case, it's just a batch file that calls two programs (the
C++/C converter, then the C compiler). In a more general case, it's a
simple setup for a makefile to create the result through one more step.

For me, this doesn't look any different than a native C++ compiler or a
normal C compiler. The one additional step is done automatically by my
build environment, and once set up, I won't really think about it a lot.

Definitely... but wasn't it you who asked for a C++ compiler? If this does
what it says it does, that's your C++ compiler for any processor that has a
C compiler.
