Yes.. there are some differences, but if your very careful with your typing..
C can be compiled with a C++ compiler.

printf("sizeof('x') == %d\n", (int) sizeof((char)'x'));

gives the same output of 1, with gcc and g++.

I really don't want to be a troll.  I still espouse that compiling a C program
with a C++ compiler even if you never actually run it that way is a definite
advantage to catch type checking problems.
