The patch in summary is touching both Makefile.in and Makefile.am, probably to avoid autotools rebuild.
This treatment is usually reserved for a few selected system packages that cannot have their autotool scripts rebuilt.
This _could_ cause maintainermode-driven rebuild (see http://blog.flameeyes.eu/articles/2008/06/13/maintaner-mode ), which is something we should be avoiding as much as possible.
Please just patch Makefile.am and/or configure.in/.ac and rebuild autotools, unless you have very good reasons not to.
P.S.: also -fix-sandbox-violation
Diego, I'll clean up the files/ directory soon as bug 233181 (stabilization of =taglib-sharp-220.127.116.11 which doesn't use the mentioned patches) has been completed.
taglib-sharp-18.104.22.168 is now stable.
This has been fixed.
