Oh right, thanks. Sorry. I didn't realise that you
were saying it didn't work at all, I thought you
were saying that there were warnings.
According to my override directory (which has the same structure as
the distribution directory but has files with the same names, hence
overriding them) I have overridden Socket.pm, but only to add:
$VERSION=1.3; # Damned lies.
What should be happening is:
LWP::Socket IS-A ::Socket
& ::Socket IS-A ::WinSock
I'm really busy at the moment but I will get back to looking at this.
Off the top of my head, I can't remember where LWP::Socket gets its
Socket definition from. Mine doesn't have the addition that you
mention but it still works. Can't tell you why right now.

Yes, I get this and some others as well, which I ought to address:
Use of uninitialized value at
C:\win32app\dev\perl-extra-libs\standard/LWP/MediaTypes.pm line 49.
Use of uninitialized value at
C:\win32app\dev\perl-extra-libs\standard/LWP/MediaTypes.pm line 49.
- these are because of $HOME -- Gisle can we please avoid the warning
if neither $HOME or $LOGDIR are set?
Subroutine is_info redefined at
C:\win32app\dev\perl-extra-libs\standard/HTTP/Response.pm line 180.

I don't know about these.

All I can say at the moment is that the lwpWin32.pl
script invokes AutoSplit on each module. This creates
a shadow directory tree under lib/auto and creates in
this a directory for each module and in these directories
a file for each procedure. The autosplit.ix file allows
the AutoLoader to find out the mapping between filenamez
and procedures and also gives the timestamp of when the
AutoSplit was performed.
Quite why the autoplit.ix file for the LWP/Socket.pm
I don't know. I haven't had time to look.
