According to Eric Blake on 3/25/2008 9:30 PM:

| Thanks for this portability analysis. I agree that it is a violation of
| POSIX; perhaps someone should report this to the busybox maintainers.
| Meanwhile, I'm documenting it for future reference:
|
There's several other places in autoconf that violate this. One in the
testsuite in foreign.at, to ignore the 'Libtool' test if the version is
too old. Several in m4sh.m4, for the sed versions of basename and dirname
(I don't have access to busybox at the moment, so I don't know if
busybox's basename/dirname are adequate enough to avoid the sed
implementation). Should we follow our own advice and not use s//\1/?

Don't work too hard, make some time for fun as well!
