, or is it sufficient to
entirely delete libtool's IFS initialization in favor of m4sugar's, thanks
to Paolo's recent cleanups to use m4sugar as documented?

According to Eric Blake on 11/22/2008 7:31 AM:
Maybe a better suggested test would be one that checks for either print or
printf (that way, a Solaris machine will let ksh pass the suggested test).
Since the overall test is running with stderr
that doesn't eat \. But
that doesn't help if you are doing a Solaris-mingw cross. I'm also
stumped on thinking of any better alternative, though.

Try './configure --disable-nls', and see if that helps.

quadrigraphs everywhere. So
I'm okay with this patch as-is.
That said, it would be nicer if libtoolize could use autom4te --trace rather
than sed scripts to learn some of what it scans from configure.ac, but that's
unrelated to this patch series...

sources.
Looks sane to me (and it gives M4sh a bit more freedom; we've already had
patches in the past month where we intentionally added bulk to M4sh to work
around libtool's sh.test, and I would like to break that reverse dependency).

This move seems a bit unrelated to the others and a bit more cosmetic in
nature, but I guess it's okay as part of this patch.

be based on 'printf', even if a shell has a builtin 'echo' that
fills the job. Is it worth still checking whether 'echo' fits the bill, in
case it can avoid the forks of lt_func_ECHO?
