New Revision: 50832
Added:
python/trunk/Mac/Modules/MacOS.c
- copied unchanged from r50783, python/trunk/Mac/Modules/macosmodule.c
Removed:
python/trunk/Mac/Modules/macosmodule.c
Log:
Fix for bug #1525447 (renaming to MacOSmodule.c would also work, but not
without causing problems for anyone that is on a case-insensitive filesystem).
Setup.py tries to compile the MacOS extension from MacOSmodule.c, while the
actual file is named macosmodule.c. This is no problem on the (default)
case-insensitive filesystem, but doesn't work on case-sensitive filesystems.
Deleted: /python/trunk/Mac/Modules/macosmodule.c
