Congrats! :-)
Can you give us some info on your project? (mes?)
I think you mentioned TCC, scheme, own header files etc.
Did you still had to use also the old gcc 2.95.3 ?
What's the goal, and why especially that target version gcc 4.7.4 ?
As I could figure out, GuixSD is a (new) GNU package manager, right?
Just a little bit curious about your complicated looking project :-)
