// because they are used as indexes in the mangling rules table.
// don't use explicit value assignment.
//
// There are two types of library functions: those with mangled
// name and those with unmangled name. The enums for the library
// functions with mangled name are defined before enums for the
// library functions with unmangled name. The enum for the last
// library function with mangled name is EI_LAST_MANGLED.
