First of all, Perl uses pdksh on OS/2 (which has no copy builtin).
;-) Second, there is not 1 shell (CMD, 4OS2); third, this behaviour is
settable, and few programmers would know the default.

Anyway: the "standard" shell (CMD) overwrites without prompt.

Fails setting a proper $! $^E (like any other builtin).

One can define File::Copy::copy_overwrite().

Technically, this is 1-bit edit of os2/os2.c.  But I care about
backward-compatibility much, so would like to see a pressing argument
to do so.

Hope this helps,
