 Unnamed bit fields can't be referenced, and their contents at run time are unpredictable. They can be used as "dummy" fields, for alignment purposes. An unnamed bit field whose width is specified as 0 guarantees that storage for the member following it in the *struct-declaration-list* begins on an **`int`** boundary.

 The ISO C99 standard lets an implementation choose whether a bit field may straddle two storage instances. Consider this structure, which stores bit fields that total 64 bits:

 To use the `pack` pragma to specify packing other than the packing specified on the command line for a particular structure, give the `pack` pragma, where the packing size is 1, 2, 4, 8, or 16, before the structure. To reinstate the packing given on the command line, specify the `pack` pragma with no arguments.
