-/* Define this if you wish to imitate the way many other C compilers handle

-
-   The behavior is that the type written for a bitfield (`int', `short', or
-   other integer type) imposes an alignment for the entire structure, as if the
-   structure really did contain an ordinary field of that type.  In addition,
-   the bitfield is placed within the structure so that it would fit within such
-   a field, not crossing a boundary for it.
-
-   Thus, on most machines, a bitfield whose type is written as `int' would not
-   cross a four-byte boundary, and would force four-byte alignment for the
-   whole structure.  (The alignment used may not be four bytes; it is
-   controlled by the other alignment parameters.)
-
-   If the macro is defined, its definition should be a C expression; a nonzero
-   value for the expression enables this behavior.
-
-   Note that if this macro is not defined, or its value is zero, some bitfields
-   may cross more than one alignment boundary.  The compiler can support such
-   references if there are `insv', `extv', and `extzv' insns that can directly
-   reference memory.
-
-   The other known way of making bitfields work is to define
-   `STRUCTURE_SIZE_BOUNDARY' as large as `BIGGEST_ALIGNMENT'.  Then every
-   structure can be accessed with fullwords.
-
-   Unless the machine has bitfield instructions or you define
-   `STRUCTURE_SIZE_BOUNDARY' that way, you must define
-   `PCC_BITFIELD_TYPE_MATTERS' to have a nonzero value.
-
-   If your aim is to make GNU CC use the same conventions for laying out
-   bitfields as are used by another compiler, here is how to investigate what

-
-        struct foo1
-        {
-          char x;
-          char :0;

-                  sizeof (struct foo2));
-          exit (0);
-        }

-   If this prints 2 and 5, then the compiler's behavior is what you would get

-/* Define this if you wish to imitate the way many other C compilers handle
-   alignment of bitfields and the structures that contain them.
-
-   The behavior is that the type written for a bitfield (`int', `short', or
-   other integer type) imposes an alignment for the entire structure, as if the
-   structure really did contain an ordinary field of that type.  In addition,
-   the bitfield is placed within the structure so that it would fit within such
-   a field, not crossing a boundary for it.
-
-   Thus, on most machines, a bitfield whose type is written as `int' would not
-   cross a four-byte boundary, and would force four-byte alignment for the
-   whole structure.  (The alignment used may not be four bytes; it is
-   controlled by the other alignment parameters.)
-
-   If the macro is defined, its definition should be a C expression; a nonzero
-   value for the expression enables this behavior.
-
-   Note that if this macro is not defined, or its value is zero, some bitfields
-   may cross more than one alignment boundary.  The compiler can support such
-   references if there are `insv', `extv', and `extzv' insns that can directly
-   reference memory.
-
-   The other known way of making bitfields work is to define
-   `STRUCTURE_SIZE_BOUNDARY' as large as `BIGGEST_ALIGNMENT'.  Then every
-   structure can be accessed with fullwords.
-
-   Unless the machine has bitfield instructions or you define
-   `STRUCTURE_SIZE_BOUNDARY' that way, you must define
-   `PCC_BITFIELD_TYPE_MATTERS' to have a nonzero value.
-
-   If your aim is to make GNU CC use the same conventions for laying out
-   bitfields as are used by another compiler, here is how to investigate what
-   the other compiler does.  Compile and run this program:
-
-        struct foo1
-        {
-          char x;
-          char :0;
-          char y;

-
-        struct foo2
-        {

-          int :0;
-          char y;
-        };
-
-        main ()
-        {
-          printf ("Size of foo1 is %d\n",
-                  sizeof (struct foo1));
-          printf ("Size of foo2 is %d\n",
-                  sizeof (struct foo2));
-          exit (0);
-        }
-
-   If this prints 2 and 5, then the compiler's behavior is what you would get
-   from `PCC_BITFIELD_TYPE_MATTERS'.

-/* Define this if you wish to imitate the way many other C compilers handle

-
-   The behavior is that the type written for a bitfield (`int', `short', or
-   other integer type) imposes an alignment for the entire structure, as if the
-   structure really did contain an ordinary field of that type.  In addition,
-   the bitfield is placed within the structure so that it would fit within such
-   a field, not crossing a boundary for it.
-
-   Thus, on most machines, a bitfield whose type is written as `int' would not
-   cross a four-byte boundary, and would force four-byte alignment for the
-   whole structure.  (The alignment used may not be four bytes; it is
-   controlled by the other alignment parameters.)
-
-   If the macro is defined, its definition should be a C expression; a nonzero
-   value for the expression enables this behavior.
-
-   Note that if this macro is not defined, or its value is zero, some bitfields
-   may cross more than one alignment boundary.  The compiler can support such
-   references if there are `insv', `extv', and `extzv' insns that can directly
-   reference memory.
-
-   The other known way of making bitfields work is to define
-   `STRUCTURE_SIZE_BOUNDARY' as large as `BIGGEST_ALIGNMENT'.  Then every
-   structure can be accessed with fullwords.
-
-   Unless the machine has bitfield instructions or you define
-   `STRUCTURE_SIZE_BOUNDARY' that way, you must define
-   `PCC_BITFIELD_TYPE_MATTERS' to have a nonzero value.
-
-   If your aim is to make GNU CC use the same conventions for laying out
-   bitfields as are used by another compiler, here is how to investigate what
-   the other compiler does.  Compile and run this program:
-
-        struct foo1
-        {
-          char x;
-          char :0;
-          char y;
-        };
-
-        struct foo2
-        {

-          int :0;
-          char y;
-        };

-        {
-          printf ("Size of foo1 is %d\n",
-                  sizeof (struct foo1));
-          printf ("Size of foo2 is %d\n",
-                  sizeof (struct foo2));
-          exit (0);
-        }
-
-   If this prints 2 and 5, then the compiler's behavior is what you would get
-   from `PCC_BITFIELD_TYPE_MATTERS'.
