Does it inherit that bad habit libtool has with reordering flags,
such as -Wl,--as-needed ?

Announcing Dolt, a drop-in Libtool replacement which cuts build times in half
 

Hello Josh,

can we limit followups to a subset of this impressive array of mailing
lists? Say, to <libtool@gnu.org>? That would be readable at
<http://thread.gmane.org/gmane.linux.debian.devel.general/126905>.
Thanks.

Curious: can you please state which Libtool version you timed against,
and if not 2.2.x, redo timing against 2.2.2? Not that I expect wonders,
but I expect something better than what you measured.

Thanks,
Ralf
