Unfortunately, I spoke too soon about bringing these patches up to date for 
two reasons. Firstly, I actually tested their application against r75 and 
there were a couple of problems which I think I have fixed now.

However, another problem has emerged when trying to build L4Re. It appears 
that something changed between r72 and r73, and now, when I try and build 
L4Re, I get a linker error as described in the following Debian bug report:

Has anything changed in r73 that might affect the structure of generated 
binaries? The same error can also be reproduced in r74 and r75.
