Comment(by howarth@…):

 Note that the darwin10.diff patch differs from the commits to gcc
 cvs[[BR]]
 because of changes in configure[.ac] and configure.host between gcc
 4.3[[BR]]
 and gcc 4.4. The essential change is not to hard code only for darwin9
 since[[BR]]
 this causes darwin10 and later to be built with the assumptions for
 darwin8 and[[BR]]
 earlier which is clearly wrong.[[BR]]
