Actually, the warning about a missing AM_PROG_CC_C_O will be automatically
given once the user has added 'subdir-objects' to the AUTOMAKE_OPTIONS.

  - the user sees the warning about missing 'subdir-objects' option;
  - he adds it to AM_INIT_AUTOMAKE, and calls "autoreconf";
  - he now sees the warning about AM_PROG_CC_C_O that is now triggered
    by the presence of 'subdir-objects';
  - he add AM_PROG_CC_C_O to configure.ac, and calls autoreconf.

However, I see that it would be nice to try to be smarter and give
the warning right away, to save the user that potentially annoy
second bootstrap.  So I still think your suggestion is a good idea.

Thanks,
  Stefano
