And by the way, number of C/C++ implementations allow "void main(.." as a
language extension. Don't get me wrong - I strongly don't recommend using
this extention, like any unportable staff without some reason - and I
can't realize what reason is to use/allow this extention.

Heare is quote from MS Visual C/C++ help:
>>>>> begin >>>>>
A special function called main is the entry point to all C++ programs. This
function is not predefined by the compiler; rather, it must be supplied in
the program text. If you are writing code that adheres to the Unicode
programming model, you can use the wide-character version of main, wmain. The
declaration syntax for main is:
int main( );

or, optionally:
int main( int argc[ , char *argv[ ] [, char *envp[ ] ] ] );

The declaration syntax for wmain is as follows:
int wmain( );

or, optionally:
int wmain( int argc[ , wchar_t *argv[ ] [, wchar_t *envp[ ] ] ] );

Alternatively, the main and wmain functions can be declared as returning void
(no return value). If you declare main or wmain as returning void, you cannot
return an exit code to the parent process or operating system using a return
statement; to return an exit code when main or wmain are declared as void,
you must use the exit function.
