I suggest not building zlib as a target library unless libgcj is also being built as a target library, given that there should be no need to built it as a target library in isolation. It can be useful to build even GCC's target libraries when not building GCC (for example, rebuilding them with different optimization options using an installed compiler) - for libraries that don't use the host-side tm.h (all except libgcc and libobjc, I think), this is practical. -- Joseph S.
