Hello libtool,
I don't know if y'all saw this blogpost where a guy pushed
the sed regular expression handling into bash-specific
regular expressions when bash was available. He claims
there's a significant performance improvement because of
reduced forking.

There is an issue in the libtool bug tracker regarding this.
This solution only works with GNU bash. It would be good if
volunteers could research to see if there are similar solutions which
can work with other common shells (e.g. dash, ksh, zsh).
