Well, Solaris 10 and 11 don't supply them _in the file system_ and they fail
the check-default-foundry.sh test as well.

configure: Buggy version of Ghostscript detected.

  Ghostscript versions 9.00 <= x < 9.54 suffer from a rendering glitch
  that affects the AT&T troff (and groff) special character '\(lh'; see
  <https://bugs.ghostscript.com/show_bug.cgi?id=703187>.  If your
  version of Ghostscript has not been patched to fix this problem, you
  may need to work around it in groff documents you render for the
  PostScript (and, for tbl(1) tables, HTML) output devices.
  
configure: URW fonts in Type 1/PFB format were not found.

  groff font description files for the URW fonts, used by the 'gropdf'
  output driver, will not be available.  Use and embedding of fonts from
  the 'U' foundry in PDF documents generated by groff will not be
  possible.

  You can obtain the URW base 35 fonts from their GitHub project.  As of
  this writing (2023-02-15), you can find them in the 'fonts' directory
  of the following archives (choose one).

    https://github.com/ArtifexSoftware/urw-base35-fonts/archive/refs/
      tags/20200910.zip
    https://github.com/ArtifexSoftware/urw-base35-fonts/archive/refs/
      tags/20200910.tar.gz

  You may wish to check for a newer release.

    https://github.com/ArtifexSoftware/urw-base35-fonts/releases

  By default, groff will look for these fonts in the search path shown
  by the 'gs -h' command (if available) and in several directories
  specified in font/devpdf/Foundry.in).  You will need to 'make
  distclean' and re-run the 'configure' script after installing these
  fonts.

  Alternatively, you can pass the option '--with-urw-fonts-dir=DIR'
  to 'configure' to look for them in the directory DIR you specify.
  If found, the 'U' foundry will be available via the '-y' option to
  'gropdf' (accessed via the 'groff' command with the option '-P -y').
    
configure: The uchardet library was not found.

This check fails and I think we can expect it to fail because BuildFoundries
doesn't yet know how to determine what fonts Ghostscript has in its %rom%.  I
guess what is happening is that if the fonts are not found, BuildFoundries
refuses to assume that the groff font descriptions of the beyond-base-14 fonts
are reliable (and moreover, if a document actually used such fonts, the PDF
standard requires that they be embedded).

> As you stated this was a test for scenario 01 (gropdf in standard mode) I
would expect a complete default foundry and that check-default-foundry.sh
would pass but it looks like it was skipped.

I'll return to that issue in a separate comment as it affects my contrived
Debian scenario specifically.
 
> Another issue is the configure missing urw-fonts message mentions that the
paths mentioned in gs -h are searched but I believe you have now removed this
from configure (correctly).

Well, the message produced by 'configure' is vague.  It says that "groff"
looks for font files in the path reported by "gs -h".  Really it is only
gropdf that looks for them there, and that only of Ghostscript is installed. 
It was true until last week that the configure script scraped "gs -h" output
as well.  It no longer does.

https://git.savannah.gnu.org/cgit/groff.git/commit/?id=b379382ea6f91dc2408973db8eb284d56255580b

Further, the name of the Ghostscript interpreter is parameterized, so I should
probably make the message respect other 'configure'd information accordingly.

I don't feel these issues should gate 1.23.0 but they'd be nice to get in for
a 1.23.1.
