/*
* 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
