Ceph

The "long" type uses 32b on x64 Windows platforms, which means it's not large enough to store a pointer. intptr_t or uintptr_t should be used instead.

include/err.h is affected by this issue. There was a previous patch on this topic but unfortunately it didn't address all the type casts.

This was brought up by the unittest_crush test, which recently started to fail as the CrushWrapper methods use IS_ERR.
