[Python-Dev] .pyc broken on Windows -- anywhere else?

[Tim Peters]

Any Unix geek awake?  import.c has this, starting at line 640:

#if defined(O_EXCL)&&defined(O_CREAT)&&defined(O_WRONLY)&&defined(O_TRUNC)
...
	fd = open(filename, O_EXCL|O_CREAT|O_WRONLY|O_TRUNC, 0666);

I need to add O_BINARY to this soup to fix .pyc's under Windows.  Is
O_BINARY customarily defined on Unices?  I realize Unices don't *need* it,
the question is whether it will break Unices if it's there ...
