Ada is no option, since the software needs to tbe in C++ for future use 
in Windows or Linux. The reason for using FreePascal as a middle is that 
it can take the existing source with very little modifications.

But after browsing a little, it seems like FPC and C works fine. But 
linking FPC with C++ code is not yet implemented (but is mentioned).
