Pushed most of these now:

0001-WaE-Clang-empty-forloop-body.patch: trivially fixed tabs to spaces

0004-WaE-Clang-adding-int-to-a-string-does-not-append-to-.patch: added a 
follow-up to go all the way to "static char const unoinfoSuffix[]"

0005-WaE-Clang-C-linkage-warning.patch: already fixed as 
18f117ae6bde53f4427c777d7bbfca2cf6afdb04

0006-WaE-patch-CLucene-to-avoid-Clang-unused-parameter-wa.patch: it 
could be useful to have some link in clucene/CustomTarget_source.mk 
indicating that the patch has been sent upstream, too

0007-WaE-Clang-expression-result-unused.patch, 
0008-WaE-Clang-implicit-conversion-changes-signedness.patch, and 
0009-WaE-Clang-implicit-conversion-changes-signedness.patch: no comments

Only 0002-WaE-Clang-unused-variable.patch and 
0003-WaE-Clang-unused-variable.patch I did not push.  Can you change 
them as I suggested above (or just let me know if you want me to do that)?

Thanks a lot,
Stephan
