oh well, i had good reason for my own belief:
cpu% cat s4/crt0.s
/ C runtime startoff
.globl savr5
.globl _main
start:
setd
mov sp,r0
mov (r0),-(sp)
tst (r0)+
mov r0,2(sp)
jsr pc,_main
cmp (sp)+,(sp)+
clr r0
sys exit
.bss
savr5: .=.+2
it doesn't look like main returns much to me.
given that the language hadn't even got void at that
point, how else was it to be declared but
main(...)
