 - Added optional verbose output to the libsi Makefile (thanks to Tobias Grimm).
+- Made the call to pkg_config configurable via the PKG_CONFIG macro, which is necessary
+  for cross-building VDR (thanks to Tobias Grimm). Plugin authors may want to modify
+  their Makefiles accordingly by adding the line 'PKG_CONFIG ?= pkg-config' and

+  the Makefiles of the plugins that come with the VDR source.
