That would be great !
Because Pascal also does not define malloc...
By the way, how is this allocated memory freed after the call to the 
inferior function ?
Does it use another C function for this, or how is it done.
if it also need to find free then we should 
also add a NAME_OF_FREE.

   Would it be possible to add a language field containing this info ?
