Something is wrong with your unlink(), and it's not an upgrade issue,
or a question of permissions.  You shouldn't get a prompt when a system
library call fails, just a non-zero return status and (in this case)
EACCES in errno.

Before you call your vendor and complain, though--make sure that you're
not linking in a modified unlink(), or using a #define'd one.  Do you
have source?  Perhaps some well-meaning (??  !!!  #$*&^@) soul changed it.
Gak.
