Description:
------------
dba_open() failed in combination with berkeley db3 file.
db3 handler doesn't seem to work correctly. I tried to call dba_open() on a non-existing database (named database.bd). The function call dba_open("c:\database.db","c","db3") failed. The same goes for option "n" instead of "c". In both cases the file is created with a size of 0 bytes. It seems as if the handler is not able to do anything with the file. Apparently on read we get a permission failure. All users have read and write access to the file. I use Apache 2.0.49 as webserver in combination with PHP as SAPI module. 


Reproduce code:
---------------
$file = "c:\database.db";

$berk_handle = dba_open($file, "c","db3");

dba_close( $berk_handle );



Expected result:
----------------
Code should have 
- created  a database.db file (it actually has ...)
- returned a handler


Actual result:
--------------
