Each member is located to the lowest available offset allowable
according to the alignment restrictions of the member type.
“The integer type compatible with each enumerated type (C90
6.5.2.2, C99 6.7.2.2).”
If the enumeration values are all non-negative, the type is
unsigned int, else it is int. The -fshort-enums command
line option can change this.
“What constitutes an access to an object that has volatile-qualified
type (C90 6.5.3, C99 6.7.3).”
Any expression which uses the value of or stores a value to a
volatile object is considered an access to that object. There is no
guarantee that such an access is atomic.
If an expression contains a reference to a volatile object but
neither uses the value nor stores to the object, the expression is
considered an access to the volatile object or not depending on
the type of the object. If the object is of scalar type, an aggregate
type with a single member of scalar type, or a union with members
of (only) scalar type, the expression is considered an access to the
volatile object. Otherwise, the expression is evaluated for its side
effects but is not considered an access to the volatile object.
For example,
“The maximum number of declarators that may modify an
arithmetic, structure or union type (C90 6.5.4).”
No limit.
“The maximum number of case values in a switch statement (C90
6.6.4.2).”
No limit.
“How sequences in both forms of header names are mapped to
headers or external source file names (C90 6.1.7, C99 6.4.7).”
volatile int a;
a; /* access to ‘a’ since ‘a’ is scalar */
