[scilab-Users] Problems of compilation of nightly build under opensuse

[Sébastien Bihorel]

Hi Michael,

I will give the new nightly build a try this evening and let your know
whether or not I experience the same problems. In case I do, I would sent my
code and data to the bug tracking system, so you could try to reproduce
them.
