This header contains typedefs for seamless switching between 32- and 64-bit builds of Percy++.

The macros that we use to detect the build type are adapted from the discussion at: "http://stackoverflow.com/questions/5272825/detecting-64bit-compile-in-c"

sid_t

server ids

dbsize_t

blocks; words/block; bytes/word

dbbits_t

total bits in database

dboffset_t

offset into database (in bytes)

nqueries_t

number of simultanous queries

nservers_t

number of servers; privacy threshold; tau-independence
