      1. No C++ comments in C code>

        2. +Never use C++ comments in C code - not all C compilers/preprocessors +understand them. Although we're mainly concerned with C++ here, there are +several files in wxWindows sources tree which are compiled with C compiler. +Among them are include/wx/setup.h and include/wx/expr.h. + +Another thing related to C vs C++ preprocessor differences is that some old C +preprocessors require that all directives start in the first column (while +it's generally allowed to have any amount of whitespace before them in C++), +so you should start them in the beginning of the line in files which are +compiled with C compiler. +

      2. No global variables with constructors

        3. In C++, the constructors of global variables are called before the main() function (or WinMain() or any other program entry point)
