/usr/lib/libm.dylib(system.o) unused definition of _system
These are due to overriding system() per the above-described hack.
The bug appears to be repaired in OS X 10.2.6 and later (possibly in
earlier 10.2.* as well, but no systems handy to check). We #ifdef out
the substitute system() definition on 10.3 and later.
