The current location used for __rte_aligned(a) for alignment of types and variables is not compatible with MSVC. There is only a single location accepted by both toolchains. For variables standard C11 offers alignas(a) supported by conformant compilers i.e. both MSVC and GCC. For types the standard offers no alignment facility that compatibly interoperates with C and C++ but may be achieved by relocating the placement of __rte_aligned(a) to the aforementioned location accepted by all currently supported toolchains. To allow alignment for both compilers do the following: * Move __rte_aligned from the end of {struct,union} definitions to be between {struct,union} and tag. The placement between {struct,union} and the tag allows the desired alignment to be imparted on the type regardless of the toolchain being used for all of GCC, LLVM, MSVC compilers building both C and C++. * Replace use of __rte_aligned(a) on variables/fields with alignas(a).
