Problem loading a toolbox

[ycollet at freesurf.fr]

Hello,

I have a toolbox which compiles fine under scilab-5.1.
The problem arise when I try to load the toolbox.

-->link('./mysql_c.dll')
              !--error 236
link: La biblioth?¿que partag?®e n'a pas ?®t?® charg?®e: Le module  
spÚcifiÚ est
introuvable.

I have the same error when I use exec loader.sce;
I am not able to when any informations related to this problem.
MySQL is installed correctly, I have started the mysql server (I don't  
think the problem is related to the start of the mysql server).
