To be the same as bionic's. See ec37237d69289e2bb9836bfa0d071ab958234d00 The new one also no longer undef offsetof and replaces it with "((size_t) &((TYPE *)0)->MEMBER)" if __compiler_offsetof isn't defined. The problem with the old behavior are that 1. __compiler_offsetof isn't defined in linux/compiler.h even though all Android compilers support __builtin_offsetof 2. As as result, offsetof defined in stddef.h to use __builtin_offsetof is undefined and replaced here. Problem is, "((size_t) &((TYPE *)0)->MEMBER)" isn't considered a compile-time constant, and fails some code expect offsetof to be. Change-Id: I3ebb0de9e1d95305a0890a099360ff6936d24b2f
