+  <!-- On most platforms, g++ would use shared-libstdc++ by default:
+       some features (e.g. thread cancellation) are known to be broken
+       with static linking for C/C++. On the other hand, Ada uses
+       -static-libgcc by default. This static/shared mix would not work.
+       In order to fix that, we follow the choice of C++ (shared libs)
+       when C++ is in the partition.
+       For more details, see eng/gpr/gpr-issues#93 and P918-005.  -->
