New submission from Christian Heimes:
Since last week I'm getting a compiler warning in _ssl.c. The compiler warning
is related to the type of _ssl_locks_count. It's an unsigned. When I cast it to
an int like PyMem_New(PyThread_type_lock, (int)_ssl_locks_count), the warning
goes away.
gcc -pthread -fPIC -Wno-unused-result -Wsign-compare -g -Og -Wall
-Wstrict-prototypes -std=c99 -Wextra -Wno-unused-result -Wno-unused-parameter
-Wno-missing-field-initializers -I./Include -I. -IInclude -I/usr/local/include
