[Scilab-Dev] Issue with the Stack in Linux

[Vincent Lejeune]

Sorry, in fact my installation was corrupted.
I don't know why, but the SciLab binaries on kubuntu repository (version 
5.1, not 5.1.1) seems not to accept the use of SCILAB_POINTER_TYPE. However, 
everything work fine with the binary from scilab.org.
