(sizeof main == 1) because (main) is treated as a logical value. Compare:
{ if (main) yadda; }

Hi,
On a Linux system with gcc, I am just wondering why sizeof(main) can
be 1 or sizeof when applied on any function name can yield 1 ever? Or
is it only gcc's perspective to say sizeof of an implicit function
pointer to be 1 since it gives sizeof(void) to be 1 based on the
backward compatibility with the pre C99 notion that void* had its
predecessor char* and usually sizeof(char) being 1?
Also, I tried the invariably buggy code to see if at all sizeof(main)
= 1 can be realized.
