modification history
--------------------
01e,14dec09,pgh  Add EM_ARCH_MACHINE_x macro definition.
01d,05jun09,v_r  Added ELF64 support (from Professional Services EMT64 Data
                 Access project).
01c,25jul05,v_r  Updated copyright.
01b,27feb04,pad  Renamed relocation type R_386_JUMP_SLOT as R_386_JMP_SLOT as
		 per ABI.
01a,12sep01,pad  Backported from TAE 3.1 to T2.2 with necessary adaptations
                 (base version: elfI86.h@@/main/tor3_x/1).
