more problems with --create-testdir and --add-import

[Werner LEMBERG]

[gnulib commit 64911207]


Comparing the contents of the gnulib directory created by

  gnulib-tool --create-testdir \
              --dir=src/libs/gl \
              wcwidth

and

  gnulib-tool --add-import \
              --dir=src/libs/gl \
              --source-base=gllib \
              --m4-base=glm4 \
              wcwidth

I see four new files in `m4':

  gnulib-cache.m4
  gnulib-comp.m4
  gnulib-tool.m4
  onceonly.m4

Why?

Similarly, there are unexpected differences in `lib' and `build-aux':

  . `--create-testdir' uses (L)GPL2, while `--add-import' uses
    (L)GPL3

  . `--add-import' adds a `Reproduce by:' line to Makefile.am (this is
    a good thing), but the `-DGNULIB_STRICT_CHECKING=1' string is
    missing from `AM_CPPFLAGS'.  Again, this is something which looks
    strange.
