  # Transforms event_rpcgen.py failure into success for make, only if
  # regress.gen.c and regress.gen.h already exist in $srcdir.  This
  # is needed for "make distcheck" to pass the read-only $srcdir build,
  # as with read-only sources fresh from tarball, regress.gen.[ch] will
  # be correct in $srcdir but unwritable.  This previously triggered
  # Makefile.am to create stub regress.gen.c and regress.gen.h in the
  # distcheck _build directory, which were then detected as leftover
  # files in the build tree after distclean, breaking distcheck.
  # Note that regress.gen.[ch] are not in fresh git clones, making
  # working Python a requirement for make distcheck of a git tree.
