Yeah it is Platform.h.

I do recall our posix_memalign being broken (and fixed) when I first
did the WebKit port, so JSC does seem to make use of that function. So
this may or may not be an issue now, but it is worth investigating.

I'm really, really hoping to be able to allocate some Haiku
development time soon, and intend to get back on the WebKit port and
Web+, which are in pretty desperate need of some attention I think. It
is just quite overwhelming and "lower hanging fruit" are always more
tempting when brief "Haiku time" is available...
But I know I'm not alone in this lately, unfortunately. And I don't
even have kids (yet.)
