Not sure about this one. It mentions NEWSOS, giving me a hint at the time
when this code was written. (ca 15 years ago...)
I'd assume the intent was not a redefinition, but a first initial
declaration. With NEWSOS and __hpux being among the few systems
that cared to ship a declaration of strlen in their header files at all.
It went unnoticed all the years, as int and size_t are pretty compatible
on most systems -- at least for the actual sizes strings happen to have
in screen.
I'd recommend to treat it the same as K&R prototypes: historical baggage.
