Oh, sorry, I has misread the version number as "1.4.9a" *blush*!

I agree a report to the m4 list might be a good move.  But consider
that the 2.0 m4 release has been put in the back burner "until further
notice", so I'd still suggest you to only employ m4 versions in the
1.4.x series for the moment being; especially for any production use.
