There is no paper on compact.c itself, but the algorithm is not
original. If I remember correctly, it is from this paper:
F. Lockwood Morris, A time- and space-efficient garbage compaction
algorithm, Communications of the ACM, v.21 n.8, p.662-665, Aug. 1978
The only tricky part is the double inversion of pointers to infix
headers. If you really need it, I'll write up a short description and
put it on my web page.
