[M3devel] problem using -DPTHREAD

Thu Feb 15 03:28:17 CET 2007

Hi:
Yes I have rebuilded with the cm3-5.4 bootstrap and it
is so much better.
Thanks so much.
Sometimes (rarely) views on mentor dont get repainted.
But I havent found a pattern of that effect. I will
let you know as soon as I can.
I tested this on ubuntu 6.06. Soon on ubuntu 6.10.
Please Elego folks, fix the m3commit list.
Thanks,

Daniel Benavides
Bogota, Colombia
