+In out-of-tree builds gtk-doc's setup-build target copies all the content from $srcdir to $builddir.
+
+However, if some of this content is regenerated at configure time this can happen:
+
+1) configure writes new build/version.xml
+2) make compile copies content, including the tarball's src/version.xml
+ to build/version.xml, and generates gtk-doc.
+3) make install notices build/version.xml is older than configure.status,
+ so regenerates gtk-doc.
+
+gtk-doc generation is a slow process at the best of times, so doing it twice isn't good.
+
+Solve this by changing cp --force to cp --no-clobber, so setup-build only copies
+files which don't already exist.
