61358b1eaa * it's rather useless that sectiontype2options is virtual as we can't use a class type, not to mention that the classes doing the overriding are for the internal assemblers/linkers, but we need it also for external 
Thus we move the functionality of the overloads to the basemethod and remove the virtual directive; maybe we'll find a better solution in the future...

3ebcef32ba + introduced TExeSection.MemPosStr - a virtual method for converting the 
section's memory position to string for the linker map file. This can be
  overriden e.g. for segmented exe formats.

3fee990218 * on Mach-O, PECOFF and ELF platforms, write local symbols as hidden/ 
private_extern (or plain global in case of PECOFF, as the effect is
    the same there): visible across object files, but they become local
    when linked into a binary/library. This enables cross-unit inlining
    of functions accessig implementation-only symbols.

f4e26f382f + added an 'index' field to TObjSectionGroup, specifying the index of the group 
in the object file (similar to TObjSection.index, but for groups, instead of
  sections). Set the new index field, when writing .obj files with the internal
  omf object writer.

065a7b63d9 * changed the TObjSectionOfs type to be longword on i8086 
+ introduced the TObjSection.SizeLimit property. This will allow setting
  different size limits for different sections (e.g. 32-bit for the dwarf
  sections, 16-bit for the regular code and data sections on i8086).

04129b8c6e + introduce the TObjSectionOfs type - an unsigned integer, representing an 
offset in an obj file section on the current platform; equal to PUInt for now,
  but will probably change to LongWord on i8086, in order to support 32-bit
  sections (needed for dwarf debug info or when linking with 32-bit object files
  in a mixed 16-bit/32-bit application, while using the internal linker)

dd9ea88b79 * TObjSection.MemPos reverted back to qword after r33692, since it breaks the 
i8086-msdos internal linker for .exe files larger than 64kb (thanks pierre for
  investigating this issue)

87baa8c43f * in the internal assembler writer, when starting a new object file, set the

db5e67c3fe + introduced a new type TRelocDataInt for use as the 'data' parameter for 
TObjData.writeReloc; on i8086 it was changed to longint to allow using 32-bit
  relocations

c8e20dfe74 + added i8086-specific consts RELOC_ABSOLUTE16 and RELOC_RELATIVE16, which are 
aliases for RELOC_ABSOLUTE and RELOC_RELATIVE
* use RELOC_ABSOLUTE16 and RELOC_RELATIVE16, instead of RELOC_ABSOLUTE and
  RELOC_RELATIVE in the linker-related parts of the OMF support (OMF object
  reader and MZ exe output). This will make the code more readable, when 32-bit
  relocation support is added to the linker. It will also make easier to reuse
  this code for i386, in case we add an i386 target, that uses the OMF object
  format.

0d48e5f6c7 + added support to the omf/i8086-msdos internal linker for omf relocation with 
location type 3 (fltFarPointer). This isn't generated by nasm, nor by the
  internal object writer (yet), but may be generated by other
  assemblers/compilers - TASM generates it (tested with it), MASM probably also
  does.

78362ed6ae * RELOC_ABSOLUTE32 made different than RELOC_ABSOLUTE on i8086 (and fixed all 
the i8086 bugs, related to code that assumes that they are the same)
+ also added RELOC_RELATIVE32 on i8086
* RELOC_ABSOLUTE32 and RELOC_RELATIVE32 are not yet implemented in the OMF
  object writer and linker (and currently produce an internal error), but will
  be implemented in the future, as the OMF format supports both 16-bit and
  32-bit relocations
