/* 
 * Sccsid:     @(#)config.h	2.1.8.2
 * 
 * this file allows the compilation of DBGEN to be tailored to specific
 * architectures and operating systems. Some options are grouped 
 * together to allow easier compilation on a given vendor's hardware.
 * 
 * The following #defines will effect the code:
 *   TPCH              -- make will create TPCH (set in makefile)
 *   TPCR              -- make will create TPCR (set in makefile)
 *   KILL(pid)         -- how to terminate a process in a parallel load
 *   SPAWN             -- name of system call to clone an existing process
 *   SET_HANDLER(proc) -- name of routine to handle signals in parallel load
 *   WAIT(res, pid)    -- how to await the termination of a child
 *   SEPARATOR         -- character used to separate fields in flat files
 *   DBNAME            -- default name of database to be loaded
 *   STDLIB_HAS_GETOPT -- to prevent confilcts with gloabal getopt() 
 *   MDY_DATE          -- generate dates as MM-DD-YY
 *   WIN32             -- support for WindowsNT
 *   SUPPORT_64BITS    -- compiler defines a 64 bit datatype
 *   DSS_HUGE          -- 64 bit data type
 *   HUGE_FORMAT       -- printf string for 64 bit data type
 *   HUGE_COUNT        -- number of objects in DSS_HUGE
 *   EOL_HANDLING      -- flat files don't need final column separator
 *
 *   OS defines
 *   ==========
 *   ATT        -- getopt() handling
 *   DIGITAL    -- changes for DigUnix 64-bit support
 *   DOS        -- disable all multi-user functionality/dependency
 *   HP         -- posix source inclusion differences
 *   IBM        -- posix source inclusion differences
 *   ICL        -- getopt() handling
 *   MVS        -- special handling of varchar format
 *   SGI        -- getopt() handling
 *   SUN        -- getopt() handling
 *   LINUX      -- getopt() handling
 *   TANDEM     -- EOL handling
 *   U2200      -- death of parent kills children automatically
 *   VMS        -- signal/fork handing differences
 *
 *   Database defines
 *   ================
 *   DB2        -- use DB2 dialect in QGEN
 *   INFORMIX   -- use Informix dialect in QGEN
 *   SQLSERVER  -- use SQLSERVER dialect in QGEN
 *   SYBASE     -- use Sybase dialect in QGEN
 *   TDAT       -- use Teradata dialect in QGEN
