It's probably so it can compile applications that use 'socklen_t' and
applications that use 'int', and those which use 'size_t' for
historical reasons (the reason 'socklen_t' was created).

Because 'socklen_t' and 'size_t' are unsigned, and 'int' is signed,
the only compatible prototype is 'void *'.

Provided the type sizes are the same, there's no problem since the
values are always small and positive.
