To clarify, your Canadian Cross should always be using gcc's internal
limits.h, so that is not surprising.  The right question is why the
internal limits.h does not have a #include_next of the glibc limits.h
(via syslimits.h).  I don't know the answer in your case, but I do know
that the test for whether there is a system limits.h, and that therefore
gcc should use a #include_next, is a fragile one.
