Windows standalones?

[Richmond]

Every time I churn out a Windows standalone (whether on Linux or on 
Macintosh) I end up with 2 files:

libeay32.dll and ssleay32.dll

in the Windows standalone folder.

1.  What are they for /; what do they do ?

2. When I ship a Windows standalone is it necessary to include them in 
the shipment?

3.  If the answer to #2 is 'Yes' what instructions should I give end 
users about those 3 files?
