d79511f96e + Basic ld script parsing capabilities (barely enough to parse glibc2.1 'libc.so' files, lacks any error handling). 
+ Support linker input source grouping functionality.
* Promote TStaticLibrary to something like generic linker input statement, it can now hold regular ObjData or a group of other TStaticLibrary objects in addition to tarobjectreader.

1d09005542 + Implemented two-stage removal of empty exe sections. Candidates for removal are first marked with oso_disabled flag, then actually removed. Descendants of TExeOutput that override MemPos_Start may modify list of sections pending removal. In particular, the COFF-specific .reloc section no longer has to be handled in base TExeOutput class.

31d004e056 + Basic executable stack support in TExeOutput. 
+ Two stubs (TExeOutput.Load_DynamicObject and TObjInput.CanReadObjData) to override in ELF linker.
+ Stop linking if errors were detected while loading object files.
* Changed TStaticLibrary to TObject. It is never looked up by name, so hashing is redundant; moreover its name has been changed to TCmdStr, which may be trimmed by TFPHashList.

14cfe770a4 * replaced most (if not all) remaining fields/parameters in the compiler 
that deal with paths/filenames with TPathStr (= ansistring) to prevent
    cutting off long paths (no change in speed when compiling the compiler,
    1% extra memory usage)

02413c8a57 * moved maybequoted() from cutils to cfileutl and let its behaviour vary 
based on the actual target platform rather than always on the host
    platform
  * on Unix, use single rather than double quotes for quoting, so it also
    properly handles $, ! and `, which keep their special meaning when
    appearing in scripts inside double quotes
  * since sysutils.executeprocess() can only deal with double-quoted
    strings in parameters, re-quote parameters on Unix when they turn
    out not to be for scripts but for direct execution (which is most
    of the time, but unfortunately doing the reverse is not possible
    because parameters used in scripts sometimes contain script-specific
    code that must not be quoted, such as `cat link.res`)
   -> always use cfileutl.RequotedExecuteProcess() rather than
    sysutils.ExecuteProcess() in the compiler (added a bunch of dummy
    ExecuteProcess string constants to common units to prevent accidental
    usage)

239944f8d0 + Use DLL name in assembler labels used to import DLL functions/variables 
in Windows, Emx and OS2 targets.
    This fixes test failures: test/library/tlib1b.pp and lib2b.pp

    link unit TLinker.AddImportSymbol: Added symmangledname parameter.
    ogbase unit TImportSymbol.Create: Add AMangledName parameter.
    fmodule unit TModule.AddExternalImport: Add symmangledname parameter.
    fppu unit: Also put mangled name string for imported symbol.
    ppu unit: Increase PPUVersion
    utils/ppudump.pp: Adapt to PPU change above.
    systems/T_OS units: Use ImportSymbol.MangledName property to create
    import libraries or .idata sections.
