Yes, that looks like the problem.
Here is what I get on IRIX 6.5:
$ echo foo | /sbin/grep -e 'fo\?'
$ echo foo | grep -e 'fo\?'
foo
$ grep --version
grep (GNU grep) 2.5.1
on IRIX 5.3 however:
lorenz 54% echo foo | /sbin/grep -e 'fo\?'
Illegal option -- e
Usage: grep -hblcnsvi pattern file ...
...so /sbin/grep (on my /newer/ IRIX) does not handle extended
regular expressions the same way GNU grep does. If my newer one
doesn't, chances are your older one doesn't either, which is
probably why configure doesn't like it ("checking for a grep that
handles ... *-e*").
Anyway, setting GREP=/sbin/grep works fine (probably the tests are
skipped)
Yes, you are probably telling it (incorrectly) that /sbin/grep is
OK. Don't do that. :-)
(Honestly, if you are then able to build gzip I guess you are OK,
but you should probably get or build GNU grep.)
OK.
I'm still wondering how I can get away with a grep that does not
support -e. It seems it is not needed at all to build gzip?
