freefunc - name clash with Python.h

[Hal Murray]

I get a blizzard of shadow warnings if Pyhton.h is included along with evp.h.
No problems on 1.1.1g from Fedora.

They go away if I include evp.h first.

/usr/local/ssl/include/openssl/safestack.h:124:72: warning: declaration of 
‘freefunc’ shadows a global declaration [-Wshadow]
  124 |                                          sk_##t1##_freefunc freefunc) \
      |                                          ~~~~~~~~~~~~~~~~~~~^~~~~~~~

I don't know anything about that area.  Is Python's freefunc the same as 
OpenSSL's?  Is this really a warning or a disaster waiting to happen?

Trivial test program attached.
