4Subject: [PATCH] gtk-doc: don't regenerate gtk-doc in do_install
5
6In out-of-tree builds gtk-doc's setup-build target copies all the content from $srcdir to $builddir.
7
8However, if some of this content is regenerated at configure time this can happen:
9
101) configure writes new build/version.xml
112) make compile copies content, including the tarball's src/version.xml
12   to build/version.xml, and generates gtk-doc.
133) make install notices build/version.xml is older than configure.status,
14   so regenerates gtk-doc.
15
16gtk-doc generation is a slow process at the best of times, so doing it twice isn't good.
17
18Solve this by changing cp --force to cp --no-clobber, so setup-build only copies
19files which don't already exist.
