# python "import pyuno" dlopens pyuno.so as RTLD_LOCAL, so g++ exception
# handling used to not work, so pyuno.so (pyuno_wrapper) is just a thin wrapper
# that dlopens libpyuno.so as RTLD_GLOBAL; but when pyuno.so wrapper links
# against libstdc++ (which has not previously been loaded into python process),
# that resolves its _ZNSs4_Rep20_S_empty_rep_storageE to itself, but later LO
# libs (loaded though RTLD_GLOBAL libpyuno.so) may resolve that symbol to e.g.
# cppu, because they happen to see that before libstdc++; so the requirement has
# always been that RTLD_LOCAL-loaded pyuno.so wrapper implicitly load into the
# process as little as possible.
# To ensure that pyuno.so does not link against libstdc++ the dynamic link
# command invokes gcc and not g++ if there are only C objects, so
# don't add any C++ objects here!
