* dcrt0.cc: Add LoadDLLFunc statement for RegEnumValueA(). 

* net.cc: Change comments related to get_ifconf.
        (get_2k_ifconf): Eliminate `type' variable. Eliminate `sa' parameter.
        (get_nt_ifconf): Ditto.
        (get_9x_ifconf): Ditto. Rewritten.
        (get_ifconf): Chage calls to OS specific functions.

* Windows 9x:
* We originally just did a gethostbyname, assuming that it's pretty
* unlikely Win9x will ever have more than one netcard. When this
* succeeded, we got the interface plus a loopback.
* Currently, we read all
* "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Class\NetTrans\*"
* entries from the Registry and use all entries that have legal
* "IPAddress" and "IPMask" values.
