That is a surprise to me.
The CeCILL is indeed free and GPL-compatible.
This is good news.

    Scilab changed its license to CeCILL 2.0 with the release of Scilab 5.
    The GNU website lists the CeCILL 2.0 as GPL-compatible.

I'm relieved that my memory was not at fault.
What was the date?
Help-octave mailing list

The page

lists the date as 2008. Even though scilab integrated with the Digiteo lab, INRIA kept a version of scilab (now called scicoslab) which forked from Scilab version 4. The scicos block simulator (a bit like simulink in matlab), was initially seperate from Scilan itself, and INRIA released a couple of versions under a dual GPL/Scilab license before stopping distribution under the GPL. Quoting from the page

Q:  Is Scicos free software?
A: Scicos 4.2 and 4.2.1 were distributed under both the Scilab 4 license and GPL in order to be included in both Scilab 4 and Scilab 5. Scicos 4.4 is only made available in ScicosLab, a fork of Scilab 4, so Scicos 4.4 is only distributed under the Scilab 4 license. Under this license, Scicos can be used freely in commercial and non-commercial applications as long as a modified version is not distributed under a different license. See the license.txt file included in the package for more details.

Scilab 5 developed the Xcos that forked from scicos at the moment scicos itself went non-GPL.. So the Scicoslab fork of scilab and scicos itself are definitely not free software even though scilab version 5 is.
