I have an environment for cross compilation and cross Linking for Windows under Linux, the environment was built using
http://www.profv.de/mingw_cross_env/README.html -> http://www.profv.de/mingw_cross_env/mingw_cross_env-2.5.tar.gz . It works good enough for me producing working Windows console executables. The following session shows the problem reported in the summary - '-S' switche is silently ignored by 'nm'; as 'objdump' shows, the .o files are practically equivalent, so if '-S' works with Linux .o file, it should also work with Windows one.
