abd6d1800e * fixed Darwin i386 compilation with 2.4.x after r17669 (the 2.4.x Darwin 
compiler itself also generates a fpc_geteipasebx symbol), mantis #19523

9273856e84 * disallow pusha*/popa* for x86_64 (mantis #14862) 
* disallow pushfd/popfd for x86_64 (mantis #14862)
  * fixed assembling popfq with the internal assembler (it needs a rex.w
    prefisx, while pushfq doesn't)
  * changed the default opcode size of pushf/popf/pusha/popa in
    {$asmmode intel} from "native size" to 16 bit (compatible with Intel
    manuals and Kylix; in AT&T mode, the default size for those operations
    remains the native one)
  * changed pushf/popf in rtl/i386/* into pushfd/popfd because of the
    previous change

92ff07deaf * several fixes by Pierre Pede (parts of his patch to mantis #12492) 
o fixed gprof under linux/i386
    o fixed pic-compilation of the linux/i386 rtl
    o initialisation of linux shared libraries is now possible with pic-code

c2c68ddb8f - removed FPC_NEW_BIGENDIAN_SETS define and if(n)defs 
* left old cpu-specific set helper code under ifdef FPC_OLD_BIGENDIAN_SETS
    in case someone wants to write new assembler set helpers (although most
    of them should be optimally generated by the compiler already if
    http://wiki.freepascal.org/FPC_HowToDo#Bit.28field.29_getting.2Fsetting_primitives
    are optimally implemented)

+ assembler implementations of DivMod for i386

0597c300f4 * applied feature dependencies patch by Sven Barth from mantis #13673 : 
o i386/i386.inc used a function (fpc_truely_ansistr_unique) is now
     only included if FPC_HAS_FEATURE_ANSISTRINGS is enabled (all other
     platforms use the Pascal-only implementations)
   o inc/heap.inc relied on threading
   o inc/threads.inc relied on exceptions, consoleio and stackcheck
   o inc/system.inc: just a feature-related "variable not used"-hint

22aacd2a60 * return 0 for length(pchar(0)), like Kylix does (using corrected and 
multi-platform version of patch in r12461, which caused the i386 version
    of fpc_pchar_length to return 0 in all cases, which used tabs, and did
    not include a test case)

5dc6e54925 * Removed inline for procedures with assembler or formal parameters, since inline is not supported for them (compiler warns about that now). Even if there is no inline modifier in interface declaration of procedure, it is possible to specify inline in procedure implementation if needed (e.g. for generic implementations) and inlining will work for them.

c35e0bf712 - removed fclex at the end of fpc_exp_real because it makes that routine 10+ 
times slower on P4/Athlon XP cpus, and removing it does not cause any test
