+# 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!
