The question is whether any of the code was the result of creative
activity by Van Engelen. Only then does copyright apply to the
code. A purely mechanical translation of your XML to some C statements
is not copyrighted, and then a GPL statement is irrelevant.
For example a straightforward Pascal-to-C translator that merely
takes "for x := 1 to 5 do" and turns it into "for (x=1; x < 5; x++)"
does not contain the result of creative activity. Therefore the
author of such a translator cannot claim any copyright interests
in the C output.
The creator of a LOGO to C translator that takes "SHOWTURTLE
REPEAT 5 FORWARD 1" and turns it into a complete graphical program
would certainly be able to impose licensing terms on such a program.
Libraries like libgcc and libstdc++ are the result of creative
activity. So a derivative work of those libraries can only be
distributed under GPL.
