Looks fine. Our front end will prettyprint your C-- but I'm not sure
if the result is valid C-- or if the prettyprinter is more for
debugging. In any case
qc-- -pp
will do something as documented on the qc--internals man page.

QC-- expects that your run-time system will be written in C
and will probably want control first.
You can 'export H as main' but you will need to give it the C calling
convention for both the procedure definition and the return.
Here's an example from our test suite:
foreign "C" main(bits32 argc, "address" bits32 argv) {
bits32 x, y;
bits32 n, m;
n, m = 987, 33;
x, y = divmod(n, m);
foreign "C" printf("address" answer, n, m, x, n, m, y, x * m + y);
foreign "C" return(0);
}
