[issue39961] warning: this use of "defined" may not be portable (Mac OS)

New submission from Clem Wang :

pyenv install 3.8.2
results in:

The real problem is on line 199 of
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/pthread.h

/*  */
#define _PTHREAD_SWIFT_IMPORTER_NULLABILITY_COMPAT \
defined(SWIFT_CLASS_EXTRA) && 
(!defined(SWIFT_SDK_OVERLAY_PTHREAD_EPOCH) || (SWIFT_SDK_OVERLAY_PTHREAD_EPOCH 
< 1))


I'm not sure if this is a problem for Apple to fix or whether the Python build 
needs to be more tolerant of warnings.
