The file db/ECO may exist, but it is corrupt. I get this error on windows if I first create a file called db/ECO. On Linux, I get a different message: 
Uncaught exception from user code:
        tie said Couldn't open ./db/ECO: Inappropriate ioctl for devic
+e

Also, on Linux I can create the file with touch to create an empty file, and that solves the problem. However, on Windows, an empty file isn't good enough - empty files still throw back the same error.

But the error goes away if I properly create the file as a correct DB_File: 

C:\temp\t>del db\ECO

C:\temp\t>perl -MDB_File -e "tie(%E,q(DB_File),q(db/ECO))"

C:\temp\t>perl test.pl
no output

So I think that's your problem - this ECO file isn't a valid DB file, and there's something a slight bit off about the way that DB_File sets $! on Windows, such that it gives the wrong error message. (Probably all that confusion about errno vs. bsderrno that goes on with dbm stuff)
