+- Patch 1046644: distutils build_ext grew two new options - --swig for
+ specifying the swig executable to use, and --swig-opts to specify
+ options to pass to swig. --swig-opts="-c++" is the new way to spell
+ --swig-cpp.
+
- Patch 983206: distutils now obeys environment variable LDSHARED, if
it is set.
