	OK, this thing has my head spinning. I use Microsoft 'C' with full
warnings. I do something easy like:

#include <stdio.h>
#include <process.h>
int main(void)
{
	(void) printf("Hello world\n");
	exit(0);
}

	And the darn thing complains that I'm not returning a value.
	So in order to make the compiler shut up, I have to:

#include <stdio.h>
#include <process.h>
int main(void)
{
	(void) printf("Hello world\n");
	exit(0);
	/* NOT REACHED */
	return(0);
}
	This seems like a heck of an overkill to produce 'hello.c' without
any warnings. So how do YOU 'exit' a program? Granted, in SOME implementations,
a 'return' from main places the return value in the program's exit status,
but I'm not sure that it is universal. I thought that was was 'exit' was for.
	I realize what the compiler is complaining about, but the solution
seems to be bad coding practice. (My Unix compiler will cough on the above
with a 'Statement not reached' warning...).
	Any thoughts?
