// ===============================================================================

// 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)
|
|
// Clang
|
|
//
|
|
//
|
|
// USAGE:
|
|
//
|
|
// struct StructToBePacked {
|
|
// } PACK_STRUCT;
|
|
//
