  Carbon: usage of menu bars can cause exceptions to be thrown
  Mac: compile fix
  Fix build
  JPEG plugin: Use switch() instead of if()
  don't try to build corewlan plugin when corewlan was not found at configure
  Avoid conversion to/from QChar in the cn codec to unicode
  Avoid memory allocations in conversion from Gb2312/Gb18030 to unicode
  fix corewlan detection error when building for 10.5 when 10.6 is also
  fixed treatment of zlib on Mac when crossbuilding
  Partial overloading support for qdbus cli tool.
