Bug ID: 110180
Summary: On Fedora 38, egrep is now obsolescent
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: dcb314 at hotmail dot com
Target Milestone: ---
Fedora 38 has decided that egrep is obsolescent and grep -E
is preferred.
I tried a gcc trunk build of c, c++ and fortran.
$ grep -E "^Config|egrep is obsolescent" mk.out

This might be worth fixing. OTOH, I am sure there are many systems where
egrep is very much not obsolescent.
