diff Python/import.c @ 14921:3db8b8031a6a legacy-trunk
The 2.0b2 change to write .pyc files in exclusive mode (if possible)
unintentionally caused them to get written in text mode under Windows.
As a result, when .pyc files were later read-- in binary mode --the
magic number was always wrong (note that .pyc magic numbers deliberately
include \r and \n characters, so this was "good" breakage, 100% across
all .pyc files, not random corruption in a subset). Fixed that.
