I am not sure from which version of Mathematica on, the old functions cannot be used; in any case I could not compile the tm_mathematica.c with the libMLi3.a choice without these changes in the case of  Mathematica 10.0.0.0). I suppose these changes need to be done also if one wanted to use the stock tm_mathematica.c provided in a TeXmacs installation.

The wrapper is attached. (note that creating a symlink to MathKernel does not work). After doing this, TeXmacs offers the Mathematica session in its list of supported sessions.

Unfortunatelly, the session does not return results of computations; instead it shows a “busy…” message (see the attached screenshot).
