These macros evaluate their arguments only once, so that they behave like
functions with respect to side-effects (e.g., `isqrs(x++)' is safe). With
the exception of isann(), each macro uses a table; to avoid wasting space
in programs compiled from more than one source, try to keep all references
to these macros in a single source file so that multiple instances of the
tables are not required. To save even more space, simply define the unneeded
macros before including this file (e.g., `#define map1').*/
