[Octave-bug-tracker] [bug #63174] New build warnings about egrep with grep 3.8

[Arun Giridhar]

Follow-up Comment #1, bug #63174 (project octave):

The relevant lines in config.log:

configure:15790: checking for egrep
configure:15858: result: /usr/bin/grep -E

...

config.status:3846: creating build-aux/subst-script-vals.sh-tmp
config.status:3846: creating config.h
config.status:4060: executing depfiles commands
config.status:4137: cd .       && sed -e '/# am--include-marker/d' Makefile   
     | make -f - am--depfiles
egrep: warning: egrep is obsolescent; using grep -E
egrep: warning: egrep is obsolescent; using grep -E

...

egrep: warning: egrep is obsolescent; using grep -E
egrep: warning: egrep is obsolescent; using grep -E
config.status:4142: $? = 0
config.status:4137: cd libgnu       && sed -e '/# am--include-marker/d'
Makefile         | make -f - am--depfiles
config.status:4142: $? = 0
config.status:4060: executing libtool commands
config.status:4060: executing oct-conf-post-private.h commands


Running "make" invoked a fresh set of them.

It looks like configure is correctly detecting "grep -E" but calling "egrep"
anyway.
