Hi,

Why do all C programs call __main?  The change logs seem to say __main
is for C++ programs and shared libraries.

The reason I care or even know about this is that I'm using gcc2 to
build mach kernels which are not linked against gcc's libraries.
Thus, I either have to stick a null definition of __main in mach's
libraries or convince you that two wrongs don't make a right.  I
clearly don't need whatever __main provides and it's a bug that I
should even have to think about it.

A less intrusive approach to this might be to fold __main into
__start.  Then if you don't link with the gnu __start (or whatever
function is in crt0), you don't have to worry about __main.

Chris
