Right now I checked how grep is built in openSUSE via
"configure --disable-silent-rules --without-included-regex"
see the grep RPM package source files at

https://build.opensuse.org/package/show?package=grep&project=openSUSE%3AFactory

in particular the file grep.spec of Package grep

https://build.opensuse.org/package/view_file?expand=1&file=grep.spec&package=grep&project=openSUSE%3AFactory


In contrast gawk is built in openSUSE without "--without-included-regex"
because it seems there is no such configure option for gawk.

See the file gawk.spec of Package gawk

https://build.opensuse.org/package/view_file?expand=1&file=gawk.spec&package=gawk&project=openSUSE%3AFactory


I do not care too much which kind of locale specific ordering
or collating or regex behaviour is actually implemented
as long as it works consistently in grep, gawk, sed, bash,...

I would very much appreciate it if grep, gawk, sed, bash,...
could agree on one same behaviour and provide clear
documentation for those who compile it what the
"commonly accepted upstream behaviour" is so that
the binaries get built with that same behaviour
by all distributors who like to be in compliance
with upstream decisions.
