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