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