79 * Stuff to handle large architecture machines; the constants were generated
80 * on a 32-bit machine and must correspond to the protocol.
88 * Definition of macro used to set constants for size of network structures;
89 * machines with preprocessors that can't handle all of the sz_ symbols
90 * can define this macro to be sizeof(x) if and only if their compiler doesn't
91 * pad out structures (esp. the xTextElt structure which contains only two
92 * one-byte fields). Network structures should always define sz_symbols.
94 * The sz_ prefix is used instead of something more descriptive so that the
95 * symbols are no more than 32 characters long (which causes problems for some
96 * compilers and preprocessors).
98 * The extra indirection in the __STDC__ case is to get macro arguments to
99 * expand correctly before the concatenation, rather than afterward.
