New Revision: 43709
Modified:
python/trunk/Lib/ctypes/__init__.py
python/trunk/Lib/ctypes/_loader.py
python/trunk/Modules/_ctypes/_ctypes.c
Log:
Expose RTLD_LOCAL and RTLD_GLOBAL always from the _ctypes extension module.
If RTLD_LOCAL is not #defined in any header file (Windows), set it to 0.
If RTLD_GLOBAL is not #defined, set it equal to RTLD_LOCAL.
This should fix ctypes on cygwin.
