In general, yes.  BUT in ANSI-C, main() is not an ordinary function.
`main' is a magic name indicating that this is the program entry point.
It must be defined as either `int main(void)' or `int main(int, char **)'
(I'm not sure if `int main(int, char **, char **)' is strictly legal).
The compiler is also free to insert additional code into main to
perform program initialisation (eg calling C++ static constructors).
On many systems, gcc inserts a call to __main() for this purpose.
