Readme should say it need help2man (to build automake)

[dufresnep]

Got that first trying to build 12.2.0 on Fedora 39 (beta):

config.status: creating t/wrap/automake-1.15
  GEN      bin/automake
  GEN      bin/aclocal
  GEN      t/ax/shell-no-trail-bslash
  GEN      t/ax/cc-no-c-o
  GEN      runtest
  GEN      doc/aclocal.1
  GEN      doc/automake.1
  GEN      lib/Automake/Config.pm
  GEN      doc/aclocal-1.15.1
help2man: can't get `--help' info from aclocal-1.15
Try `--no-discard-stderr' if option outputs to stderr
make: *** [Makefile:3687: doc/aclocal-1.15.1] Error 2

Now trying to install help2man that was not installed.

Not so simple... still having this issue after installing help2man:

config.status: creating t/wrap/automake-1.15
  GEN      bin/automake
  GEN      bin/aclocal
  GEN      t/ax/shell-no-trail-bslash
  GEN      t/ax/cc-no-c-o
  GEN      runtest
  GEN      doc/aclocal.1
  GEN      doc/automake.1
  GEN      lib/Automake/Config.pm
  GEN      doc/aclocal-1.15.1
help2man: can't get `--help' info from aclocal-1.15
Try `--no-discard-stderr' if option outputs to stderr
make: *** [Makefile:3687: doc/aclocal-1.15.1] Error 2
root@fedora:/home/paul/Téléchargements/build-djgpp-master1# help2man
`help2man' generates a man page out of `--help' and `--version' output.

Usage: help2man [OPTION]... EXECUTABLE

 -n, --name=STRING       description for the NAME paragraph
 -s, --section=SECTION   section number for manual page (1, 6, 8)
 -m, --manual=TEXT       name of manual (User Commands, ...)
 -S, --source=TEXT       source of program (FSF, Debian, ...)
 -L, --locale=STRING     select locale (default "C")
 -i, --include=FILE      include material from `FILE'
 -I, --opt-include=FILE  include material from `FILE' if it exists
 -o, --output=FILE       send output to `FILE'
 -p, --info-page=TEXT    name of Texinfo manual
 -N, --no-info           suppress pointer to Texinfo manual
 -l, --libtool           exclude the `lt-' from the program name
     --help              print this help, then exit
     --version           print version number, then exit

EXECUTABLE should accept `--help' and `--version' options and produce output on
stdout although alternatives may be specified using:

 -h, --help-option=STRING     help option string
 -v, --version-option=STRING  version option string
 --version-string=STRING      version string
 --no-discard-stderr          include stderr when parsing option output
