[Message part 1 (text/plain, inline)]

Hi,

I found that GNU sed does not compile on platforms with <getopt.h> or
getopt_long. For example on AIX:

    make[2]: Entering directory '/home/collinfunk/sed-4.9.51-0f74-modified'
      CC       sed/sed-sed.o
    sed/sed.c:20:10: fatal error: getopt.h: No such file or directory
       20 | #include <getopt.h>
          |          ^~~~~~~~~~
    compilation terminated.
    make[2]: *** [Makefile:6188: sed/sed-sed.o] Error 1
    make[2]: Leaving directory '/home/collinfunk/sed-4.9.51-0f74-modified'
    make[1]: *** [Makefile:6425: all-recursive] Error 1
    make[1]: Leaving directory '/home/collinfunk/sed-4.9.51-0f74-modified'
    make: *** [Makefile:3595: all] Error 2

This is because the following commit:

        * bootstrap.conf (gnulib_modules): Remove getopt module, depracated in
        https://git.savannah.gnu.org/cgit/gnulib.git/commit/?id=0abc38bd2a1398f0
        [...]

The deprecation of getopt was because it split into getopt-posix and
getopt-gnu. GNU sed uses <getopt.h> and getopt_long, so we need
getopt-gnu.

I have attached a patch that fixes this. I added a note in NEWS since
the 4.9 was released after that commit so the tarball won't build on
platforms like AIX.
