in repository groff.

commit f107252c3c0d3b70236e0db5a56238a406231bf5
Author: G. Branden Robinson <g.branden.robinson@gmail.com>
AuthorDate: Fri Nov 15 15:57:34 2024 -0600

    Drop now-unused Autoconf macros.
    
    * configure.ac: Stop expanding `GROFF_AWK_NOTICE`,
      `GROFF_PDFROFF_DEPENDENCIES_CHECK`, and `GROFF_PDFROFF_PROGRAM_NOTICE`
      macros.  Drop `AM_CONDITIONAL` with `USE_PDFROFF` argument.
    
    * m4/groff.m4 (GROFF_AWK_NOTICE, GROFF_AWK_PATH, GROFF_AWK_PREFS)
      (GROFF_PDFROFF_DEPENDENCIES_CHECK, GROFF_PDFROFF_PROGRAM_NOTICE): Drop
      unused macro definitions.
