How to make c++ realize empty character constant ''?

The *GNU's* C++ compiler name is g++. Clang's C++ compiler name is clang++
for example. (Microsoft Visual C++'s compiler name is lc.exe.) ‘c++’
usually a symlink on the compiler the system primarly built with. (or
something like that.)

the cpp (as a command) usually used to compile C codes, and it is heavily
used by MacPorts (where the program was written in C) since MacPorts
compiles the ports from source right there, on your Mac. One could use c++
(or g++) instead of cpp for C.

However, the GNU compiler is also capable to select the proper language and
use the proper tools for compillation, so GNU's cpp will compile… I believe
Fortran, or even Java, if the proper alternative GNU compiler present. I've
never used this capability this extremely though, and not aware wether
other compilers are capable to do so.

Xcode used to ship GNU's C++ compiler. Now it is only a symlink to clang++.
