11eb1a4179 + added some i8086 memory model specific defines in strings.inc and 
stringss.inc, used by the assembler routines (they are already defined in

nickysn
024ebb287e + implemented set_jmp and long_jmp on win16 via the Catch and Throw winapi 
functions, which provide the same functionality, but are safe to use in all
  windows modes (e.g. they include the magic for handling jumps to discarded
  or moved code segments in real mode)

2f83e2efc9 * use 'seges' instead of db 26h. It is actually supported, but for some reason, 
unlike TP7's inline asm, in FPC it doesn't work on the same line as 'lodsb'.

0255eb880e - Removed mathuh.inc files which are identical for all targets (except m68k, see below), their contents moved into math.pp.

a176c2d4f5 + add overloaded versions of HexStr(pointer) for i8086 near and far pointers 
- rm ifdefs for i8086 far code memory model when doing stack traces. The

  CodePointer type.

015c7e951a * Changed the default packset setting to 1 and disabled the padding of 3-byte 
sets to 4 bytes on 16 and 8-bit CPUs. This is compatible with Turbo Pascal 7
  and Delphi 1.

a85bb98aa6 * patch from Max Nazhalov with improvements to the i8086 64-bit division: 
since [unnormalized] n >= 0x10000 now, we have
   1. lzv<=47, so all code that makes shifts by >= 48 is dead;
   2. q3=0, so main loop can be executed just 3 times instead of 4.
