[PATCH 0/4] Patches for handling property attributes correctly in objc.

[Jean-Charles BERTIN]

These are my patches to change ABI for property attributes on Objective-C.
Actually, the behavior is clearly not the same as MacOS X. So this is my
effort to correct this. These patches are strongly correlated with these I
pushed on gnustep-dev at gnu.org mailing list.
I really tried not to break old existing codes by introducing a new version
(1.8) for gnustep runtime. 

Jean-Charles BERTIN (4):
  Fixed compilation warning.
  Changed property attributes to an int because they were truncated when
    casted to a char.
  Fixed ABI for objc property attributes to mimic MacOS X behavior.
  Cleanup property attribute flags.     Fixed getter/setter in property
    attribute.
