  25 # that dlopens libpyuno.so as RTLD_GLOBAL; but when pyuno.so wrapper links
  26 # against libstdc++ (which has not previously been loaded into python process),
  27 # that resolves its _ZNSs4_Rep20_S_empty_rep_storageE to itself, but later LO
  28 # libs (loaded though RTLD_GLOBAL libpyuno.so) may resolve that symbol to e.g.
  29 # cppu, because they happen to see that before libstdc++; so the requirement has
  30 # always been that RTLD_LOCAL-loaded pyuno.so wrapper implicitly load into the
  31 # process as little as possible.
  32 # To ensure that pyuno.so does not link against libstdc++ the dynamic link
  33 # command invokes gcc and not g++ if there are only C objects, so
  34 # don't add any C++ objects here!
