In addition, the exacly same code should behave identically
with both the Jul2015 release branch and the pythonudf develpment
branch --- provided you checked out both branches from the Mercurial
repository.
In case you used the source tarball for the Jul2015-SP2 release,
things are slightly different.
Strict (for good reasons!) compiler options are by default only
enabled with Mercurial source, but not with source tarball.
You can (and should, if you develop code yourself) enable them
also with source tarballs by running configure with --enable-strict .
NB, compiler warning and error not "nasty" but very helpful to write correct code.
