[Texmacs-dev] scilab plugin broken

[yves]

Hello texmacs developpers!

Unfortunately the Scilab interface is broken in last texmacs 
(TeXmacs-1.99.10-C.tar.gz from texmac site). Tested with Scilab 6.0.1 
packaged in devuan, Scilab 6.0.2 and 5.5.2 from scilab website.

After Openning a session, texmacs show a "Buzy..." frame just above the 
"Scilab]" one. Same when sending a command to Scilab through the 
session.

When starting the session, a scilab window opens and the console says:
--------------------

check or define function %c_c_function for overloading.

Any solution ?
