   6 # as with read-only sources fresh from tarball, regress.gen.[ch] will
   7 # be correct in $srcdir but unwritable.  This previously triggered
   8 # Makefile.am to create stub regress.gen.c and regress.gen.h in the
   9 # distcheck _build directory, which were then detected as leftover
  10 # files in the build tree after distclean, breaking distcheck.
  11 # Note that regress.gen.[ch] are not in fresh git clones, making
  12 # working Python a requirement for make distcheck of a git tree.
