Many thanks, Sergey. There is the same problem with macro
redefinition, although less likely to occur in real documents, when a
macro is defined within the Top node. Test file below.

I would like to explore forgoing the use of sed to process @ifnottex
etc., and using the --iftex option to makeinfo. Can someone explain
what "Unfortunately makeinfo --iftex --no-ifinfo doesn't work well
enough (yet), makeinfo can't parse the TeX commands, so work around
with sed." means - what TeX commands can't makeinfo parse? Contents of
@iftex shouldn't be TeX commands anyway, TeX commands would occur in
@tex.

I found another option to makeinfo that could be used to expand the
macros: "-c DUMP_TEXI=1 --macro-expand=-" - this avoids generating
Info output that is discarded, and reduces the amount of error
messages related to document structuring. Unlike "-c
TEXINFO_OUTPUT_FORMAT=plaintexinfo -o-" it will manage to output the
macro expansion even if there is an error, like "menu before Top
node". I think the "menu before Top node" error, if it is annoying,
could be best dealt with by changes in the input Texinfo files to
include the menu within the @ifnottex conditional.

\input texinfo @c -*-texinfo-*-
