There should be a file named config.log in the libstdc++-v3 and you may get
more clues fro there. Now the build scripts has built the gcc 4.2
(/home/nancy/work/build-open64-svn/osprey-gcc-4.2.0/host-unknown/gcc/xgcc)
and tried to use it to build the libstdc++ shipped with gcc 4.2 (otherwise
there will be compatibility issues between the front end and stdc++).
Basically, the system libm should be used.
