45: * This header is included only in other .h files, for convenience and for
46: * simplicity of type naming. The alternative for structures is to use tags,
47: * which are named the same as their typedef names (legal in C/C++, and less
48: * noisy than suffixing the typedef name with "Struct" or "Str"). Instead,
49: * all .h files that include this file may use the same typedef name, whether
50: * declaring a pointer to struct type, or defining a member of struct type.
51: *
52: * A few fundamental scalar types are defined here too. Neither the scalar
53: * nor the struct typedefs should change much, therefore the nearly-global
54: * make dependency induced by this file should not prove painful.
