It turns out that our two threads are connected.  In
calc++/Makefile.am, one reads:

        $(BISON) -d -ra -S lalr1.cc -o $(srcdir)/calc++-parser.cc \
          $(srcdir)/calc++-parser.yy

which includes `-S lalr1.cc -o $(srcdir)/calc++-parser.cc', which is
known not to work properly: some of the files are _not_ output in
srcdir, but in builddir.  Hence my confusion before between src and
build dirs.  Your forthcoming patch should solve this.
