e716ac6b6b * give ord->formaldef again a higher precedence than ord->floatdef 
(last convert level that is added, needs a more structural
     solution)

82a0749970 * prefer non-matching orddef conversions to orddef-to-pointer conversions 
(mantis #10002) and also to orddef-to-real conversions
    (delphi-compatible). More tests and fixes will follow later.

5bc156efea * always demote type conversions which cannot represent part of the 
source value to convert_l3, instead of only those with a destination
    type whose size is < source size (like Delphi) + test -> fixes
    toperator6 along with a host of wrong tordconst typeconversions in
    the compiler sources themselves (although most are harmless)

6e0a7bb0eb * Nil constants that are type converted to a method procvar are now 
properly converted. The conversion is done at runtime to generate
    a two pointer memory reference as result location, something
    which the code generator can handle very well, which minimizes
    the chance of side effects.

504d845e86 * Consider conversion from integer to integer te_equal, if the base types 
are equal and the range of the from type fits in the to type. I.e.
    conversion from -10..10 to shortint is considered equal. This is correct
    because in this case, the from type can be used wherever the to type is
    used, i.e. the compiler never needs to do conversion at compile or run
    time.

6555f37cff * do not search variant operators when looking for an overloaded 
operator for a non-variant type (was already intended that way,
    but checks didn't work) (mantis #7070) + tests

d87f03eef5 - removed automatic int-string, string-int and int-array conversion for 
macpas after discussion on macpascal mailing list. The only thing left
    is automatic conversion of constant strings of length 4 to 32 bit ints.
  * adapted tests to this
  * fixed FOUR_CHAR_CODE and FCC functions in MacPas unit for little
    endian
  + FourCharArray type in macpas unit wich can be used to typecast
    int's "back" to an array[1..4] of char (though the characters
    will be in reverse on little endian systems in that case)

47eb589d54 * allow implicit conversions from/to packed char arrays under the 
same conditions as from/two regular char arrays (since a packed
    char array is the same as a string in ISO Pascal)

eccbc78e04 + support for bitpacked arrays: 
+ use {$bitpacking on/+} to change the meaning of "packed"
      into "bitpacked" for arrays. This is the default for MacPas.
      You can also define individual arrays as "bitpacked", but
      this is not encouraged since this keyword is not known by
      other compilers and therefore makes your code unportable.
    + pack(unpackedarray,index,packedarray) to pack
      length(packedarray) elements starting at
      unpackedarray[index] into packedarray.
    + unpack(packedarray,unpackedarray,index) to unpack
      packedarray into unpackedarray, with the first
      element being stored at unpackedarray[index]
  * todo:
    * "open packed arrays" and rtti for packed arrays are not
      yet supported
    * gdb does not properly support bitpacked arrays
