a23630260b + "weakexternal" support for imported procedures and variables. 
the syntax is exactly the same as for "external", except for
    the keyword. It is currently only active for Darwin targets.
    It should also work at least for Linux targets, but only with
    the GNU assembler (which is why it is not activated there)
  + test for this functionality

263984f874 * fixed a_load_ref_reg for OS_S8->OS_16 for ppc32, ppc64 and sparc 
(and on ppc64 also for OS_S8->OS_32 and OS_S16->OS_32)
  * adapted tcnvint6 to check for ppc64 OS_S16->OS_32 conversion
    (the old comparison was performed using a 32 bit compare and
     therefore did not notice the wrong result)

8349cde7db * changed byte/word/longbool to be Delphi-compatible (+ similar changes 
for qwordbool) + test:
    o assigning true to such a variable now sets them to $ff/$ffff/$ffffffff
    o these types are now all signed
    o converting an integer type to a byte/word/long/qwordbool using an
      explicit type cast keeps the integer's original value stored in the
      bool, instead of forcing it to ord(true)/ord(false)
    (mantis #10233 and #10613, implemented for all architectures, testsuite
     tested for ppc32, sparc and x86)
  * fixed some places where the rtl depended on longbool(true) having the
    value 1
  * extended several boolean tests (and adapted some to no longer assume
    that byte/word/long/qwordbool(true)=1)
  + support for converting to qwordbool in second_int_to_bool for x86, ppc
    and sparc

ad5ce1adf4 * fixed a_load_reg_ref: the store size has to depend on the tosize, 
not on the fromsize (fixes webtbs/tw10072, and hopefully also
    resolves mantis #8121)

e815b923d5 * a_loadfpu_* gets two size parameters: fromsize and tosize 
* fixed downsizing the precision of floating point values
  * floating point constants are now treated using only the minimal
    precision required (e.g. 2.0 is now a single, 1.1 extended etc)
    (Delphi compatible)
