I think a warning is ok.  But moreover, I noticed other places
in Info manuals that cause problems for Info readers:

By funny coincidence, the LilyPond music glossary contains words
`*note*' emphasized by asterisks around them, where the word `note'
means a symbol for a musical tone.  But it is interpreted by the Info
reader as an Info reference, and if Info-hide-note-references=t it is
displayed as `See *'.  Even though the Texinfo manual warns about
using asterisks with the word `note', it suggests to replace it
by a phrase such as *Please notice* which is inappropriate here.
Perhaps makeinfo should produce a warning about it, but still
I don't see how the author would fix this problem.

There are many other Info manuals that have a string `*Note:'
which is treated incorrectly by Info readers.  What do you think
about interpreting a `*Note' as an Info reference only if it
has whitespace around it, i.e. if it matches the following regexp?

[ \t\n]+\*[Nn]ote[ \t\n]+

It would also solve the problem of incorrect interpreting of
the quoted ``*Note:'' string such as in the following Info nodes:

(info "(info)Cross-refs")
(info "(info-stnd)Parts of an Xref")
(info "(texinfo)Cross Reference Commands")
