New submission from Matthias Klose <[email protected]>:
building extensions statically in linking these into the python binary is
currently broken on 3.7.
I'm attaching the change that worked for me in 3.7alpha2, but doesn't work
anymore with alpha3. Currently investigating. When building extensions as
builtins, these should benefit from the knowledge about the core interpreter.
