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.


There is also this warning:

cpukit/libmisc/stackchk/check.c:455:5: warning: cast to pointer from
integer of different size [-Wint-to-pointer-cast]

This is probably an error. Could you please fix the warnings specific to
the new BSPs.

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.

Sorry, I didn’t see these when I was developing. I’ll work up some patches for them.
