C code can be generated intermediate representation too, which it appears to be in this case.  What stops you from regenerating the intermediate C code just like Leonid does?  You have the widely-available tools with source code to generate the C code.  Leonid has the widely-available tools with source code to generate the C code.  All seems to be quite good there.

Or if Leonid modifies the generated C code with scripts that the source code for the scripts are obtainable along with (or distributed with) each release of AdaStudio, so that you can invoke those scripts too, just like Leonid did.

That is only moving the question one step away, since then you could 
formulate it as 'where are the source scripts and/or instructions to 
generate the intermediate C library'. Intermediate meaning here: layer 
between Ada and the Qt C++ libraries. I wasn't assuming that there is 
something wrong with the distribution, only that there's an issue that 
needs clarification. Please note that this is not quick and unjustified 
criticism, it comes from my failed attempt to use this binding with the 
Qt libraries provided by Ubuntu (see [1]), which is one of the basic 
freedoms granted by the GPL and LGPL, and restated by Qt as:
