Problem is that we have some of the sources listed relative to $(srcdir) in Makefile.am, which breaks when enabling subdir-objects. But we can't remove the $(srcdir) either, becase these sources in question are generated from m4 sources when --enable-maintainer-mode is enabled, and $(srcdir) is thus needed so that the generated files will correctly end up in in the source tree and not the build tree. Gah! I filed https://gcc.gnu.org/bugzilla/show_bug.cgi?id=87856 to keep track of this. -- Janne Blomqvist
