It is likely that this is because some/many architectures do not
have long double support in newlib. Or have a true long double
type. This will require a newlib discussion.

This looks like code being sloppy that isn't the fault of this BSP. It is
just one where sizeof(int) != sizeof(void *).

Kinsey.. likely solution is to replace the cast/type with intptr_t or
uintptr_t.
