[Scilab-Dev] Problem using double API

[Vincent Lejeune]

It didn't work either, but I have find out what was breaking the code :

I was using the same name for scilab function and c-function, that
is to say, ocltest in Scilab called the ocltest C-function. When I changed
the name in my builder_gateway_c.sce file, everything worked as
expected.
However I don't know if this can be considered as a
"bug" , as this kind of naming convention is somehow not
recommanded...
