Hi Optikos

Thanks for all your great posts and help.

So with the Ada-Yacc/Flex, we are Berkley licensed and that's it. However i=
f I started tearing out pieces from gnat 3.14, the generated code could con=
tain GMGPL code taken from it(Likely after a lot of modification).


Let's say I wanted to implement nested sub-programs, gnat must have trampol=
ines or something in there. I could rip these out without having to write t=
hem.

This would mean that the generated code would have to be GMGPL too.

If I didn't do this, everything could be BSD but then I would have to write=
 everything from scratch and that could take quite a lot of time.

BTW, another plus with this, if gnat is not linking in any runtime, and the=
 runtime was created by the source-to-source preprocessor, all of the targe=
ts that gcc supports would be possible as long as the preprocessor was able=
 to generator the right support before it reached gnat.
