Sorry, I don't know.

"main" is a special case and the C compiler is allowed to do
special things with it.  It could, for example, link to a
different crt0.o (or equivalent) depending on the signature
of "main".  Or it could mangle the name -- the C standard
doesn't prohibit that.

That implementation is allowed, but it's not required.
