Comment 1 Bernhard Reutner-Fischer 2012-04-03 08:02:22 UTC

Benjamin,

in r185950 you said:

-vpath % $(top_srcdir)/src
-vpath % $(top_srcdir)
+vpath % $(top_srcdir)/src/c++98
+vpath % $(top_srcdir)/src/c++11

Comment 2 Bernhard Reutner-Fischer 2012-04-03 10:20:07 UTC

The patchlet below reinstates bootstrapping for me.
