Katarxhn oson afora to void main() den ksero ti exei ylopoiithei ston 
teleftaio gcc.
Afto pou ksero einai afto pou leei to standard:

"5.1.2.2.1 Program startup
1. The function called at program startup is named main. The implementation 
declares no prototype for this function. It shall be defined with no 
parameters: int main(void) { /* ... */ } or with two parameters (referred 
to here as argc and argv, though any names may be used, as they are local 
to the function in which they are declared): int main(int argc, char 
*argv[]) { /* ... */ } or equivalent,(9) or in some other 
implementation-defined manner."

To parapano shmainei oti enas compiler pou den dexetai katholou to void 
main() borei na einai ANSI C compliant.

Epishs shmainei oti kai to int main(char *p) pou egrapses einai eksisou 
lathos me to void main().

Oson afora to compile tou programmatos sou ennoeitai oti den tha eprepe na 
ginei apo thn stigmh pou h C den ypostirizei function overloading. Kai to 
programma sou exei conflicting datatypes gia thn synarthsh main.

Tora to error message einai thema tou gcc .... alla molis proseksa oti den 
xrhsimopoieis gcc alla g++ opote ta parapano mallon den isyxoun etsi akrivos.

Den thymamai ti akrivos isxyei gia thn c++ oson afora thn main() alla 
nomizo isxyei to idio, isos ligo diaforetika diatypomeno sto standard.
Alla exo thn entyposh oti o g++ den einai 100% ANSI/ISO C++ compliant etsi 
kai allios.
