utils/libmach/qdb.c compilation error for openbsd due to qdiv()

What steps will reproduce the problem?
1. try to compile latest inferno on openbsd.

What is the expected output? What do you see instead?
compilation fails on utils/libmach/qdb.c.

it contains a definition of qdiv.  openbsd also has a symbol with that name in 
/usr/include/stdlib.h.

the qdiv in utils/libmach/qdb.c was renamed to qmuldiv in revision 
135:691d0a7a1ef1, but with april 2010's revision 416:aa36ea96995c the symbol is 
again named qdiv and compilation fails again.

btw, inferno does not work properly (at all) on the latest openbsd release 
(4.8).  something seems wrong with openbsd's rfork, i'm investigating that.
