The 2-operand form was inherently unsafe. Use the 3-operand form instead, which guarantees that arbitrary filenames are supported. This also means we can remove a few instances of sysopen() which was used for exactly this reason, however, at least in theory sysopen() isn't portable. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
