The existing __rte_packed macro is then used to restore the pack value prior to the push. Instead of providing macros exclusively for MSVC and for GCC the existing macro is deliberately utilized to trigger a warning if no existing packing has been pushed allowing easy identification of locations where the __rte_msvc_pack is missing. I've decided to only add the macro to packed structs that are built for Windows. It seems there is little value in adding the macro tree wide and if new code arrives that is built on Windows the __rte_packed will flag where the preamble macro is required.
