* Add an NDK header to define INIT_FUNCTION/INIT_SECTION globally * Use _declspec(allocate(x)) and _declspec(code_seg(x)) on MSVC versions that support it * Use INIT_FUNCTION on functions only and INIT_SECTION on data only (required by MSVC) * Place INIT_FUNCTION before the return type (required by MSVC) * Make sure declarations and implementations share the same modifiers (required by MSVC) * Add a global linker option to suppress warnings about defined but unused INIT section * Merge INIT section into .text in freeldr
