// ===============================================================================
// May be included multiple times - sets structure packing to 1
// for all supported compilers. #include <poppack1.h> reverts the changes.
//
// Currently this works on the following compilers:
// MSVC 7,8,9
// GCC
// BORLAND (complains about 'pack state changed but not reverted', but works)
//
//
// USAGE:
//
// struct StructToBePacked {
// } PACK_STRUCT;
