GNU grep 3.8 warns about some regular expressions that POSIX says have
undefined effect, e.g., '\-'. Unfortunately Libtool uses regular expressions
of this form.
I'm attaching two proposed patches against libtool's current HEAD (commit
6132006b5fb6b95f31c30a972fbb829f93e1878b dated 2022-05-16). The first patch
should suffice to pacify GNU grep 3.8. The second patch fixes some other
regular expressions that GNU grep 3.8 does not warn about (I found them with
an even-pickier 'grep').
I did not look systematically for all portability bugs of this form.
