Building gm2-gcc-12 on NetBSD 9.1 Sparc

[john o goyo]

Nearly home, folks.

After a few bumps, to be reported after build, I have arrived at the 
following problem.  Makeinfo halts due to too many erros in the gm2.texi 
file.

Here is a sample.

if test "xinfo" = xinfo; then \
  rm -f doc/m2.info*; \
          makeinfo --split-size=5000000 --split-size=5000000 
--split-size=5000000 --no-headers -I/home/build/opt/gcc/bld/gm2/gcc/m2 
-I../../../src/gcc-git/gcc/doc/include \
                      -o doc/m2.info 
../../../src/gcc-git/gcc/doc/gm2.texi ; \
else true; fi

The build is using makeinfo 4.8.  Which version is recommended (or is 
something else going on)?

Sincerely,
