for most of this. I just integrated the build). This adds proper functions for the _Qp* parts of the sparc64 ABI (which handle quad softfloat). The routines work but need additional testing. However if the compiler calls these currently bad things (core dumps) will happen as gcc 2.95.3 generates bad calls for these. Until that problem is fixed in the toolchain -msoft-quad-float cannot be enabled as the default option for all builds (but the routines need to be in libc as libgcc contains some references to these and anything including it via --whole-archive will need the symbols to at least resolve).
