| nuclear@0 | 4 // May be included multiple times - sets structure packing to 1 |
| nuclear@0 | 5 // for all supported compilers. #include <poppack1.h> reverts the changes. |
| nuclear@0 | 6 // |
| nuclear@0 | 7 // Currently this works on the following compilers: |
| nuclear@0 | 8 // MSVC 7,8,9 |
| nuclear@0 | 9 // GCC |
| nuclear@0 | 10 // BORLAND (complains about 'pack state changed but not reverted', but works) |
| nuclear@0 | 11 // Clang |
| nuclear@0 | 12 // |
