comparison Python/thread_pthread.h @ 14144:31cda87e9ff4 legacy-trunk
This patch partly (some stuff went in already) ports Python to Monterey.
- Fix bug in thread_pthread.h::PyThread_get_thread_ident() where
sizeof(pthread) < sizeof(long).
- Add 'configure' for:
- SIZEOF_PTHREAD is pthread_t can be included via <pthread.h>
- setting Monterey system name
- appropriate CC,LINKCC,LDSHARED,OPT, and CCSHARED for Monterey
- Add section in README for Monterey build
