Hey Marc,

That's not really the cause. You'll have to use a c99 compiler to build
scc. Maybe yours need an option like “-std=c99”.

scc -I where/your/c/headers/files/are
(although scc isn't necessarily able to parse them atm).

Have a look at config.mk. By default it uses PREFIX=$HOME. So if you
want to install scc elsewhere, rebuild it setting the PREFIX to
elsewhere.

Reading the code.

Yes.

Any compiler following the c99 standard will work.

You may want to test it with the qbe backend for now, as most of the
work is done there atm.

Thanks!
