gcc v.11.3.0 failing - possible cause gcc or libreadline.a?

The problem was with readline not gcc
and I assume originates in myarchive.a and the required switch -lreadline in the gcc line
rather than in readline: nevertheless I reverted both libreadline-devel and libreadline7
from 8.22 to 7.03 and the problem went away.
