-Define this macro (to a value of 1) if you want the System V style

-
-The pack pragma specifies the maximum alignment (in bytes) of fields
-within a structure, in much the same way as the @samp{__aligned__} and
-@samp{__packed__} @code{__attribute__}s do. A pack value of zero resets
-the behavior to the default.
-
-A subtlety for Microsoft Visual C/C++ style bit-field packing
-(e.g.@: -mms-bitfields) for targets that support it:
-When a bit-field is inserted into a packed record, the whole size
-of the underlying type is used by one or more same-size adjacent
-bit-fields (that is, if its long:3, 32 bits is used in the record,
-and any additional adjacent long bit-fields are packed into the same
-chunk of 32 bits. However, if the size changes, a new field of that
-size is allocated).
-
-If both MS bit-fields and @samp{__attribute__((packed))} are used,
-the latter will take precedence. If @samp{__attribute__((packed))} is
-used on a single field when MS bit-fields are in use, it will take
-precedence for that field, but the alignment of the rest of the structure
-may affect its placement.
-
-The weak pragma only works if @code{SUPPORTS_WEAK} and
-@code{ASM_WEAKEN_LABEL} are defined. If enabled it allows the creation
-of specifically named weak labels, optionally with a value.
