I am seeing the following warnings (which break the build when
configured with --enable-Werror):

gnu_java_nio_channels_FileChannelImpl.c:565:
  warning: pointer of type 'void *' used in arithmetic
gnu_java_nio_channels_FileChannelImpl.c:504:
  warning: 'RawData_init' may be used uninitialized in this function
gnu_java_nio_channels_FileChannelImpl.c:503: warning:
  'MappedByteBufferImpl_init' may be used uninitialized in this function

I have not investigated them yet. But maybe they give a hint to why
things don't work on darwin?

Cheers,

Mark
