It appears that all of the problems come from ExtUtils::Manifest. I have 
not completely narrowed down the problem there, but I suspect it is a 
bug in Perl's link() implementation on MSWin32 (which EU::Manifest only 
attempts on Windows NT variants, and not Windows 9x). The problem is 
eliminated by changing the call to EU::Manifest::manicopy() in 
M::B::Base::ACTION_distclean() so that the last parameter is 'cp' 
instead of 'best'. This of course is not the correct solution, nor is 
copying the entire sub to Windows.pm just to change one line. Maybe an 
option can be set in $self->{config} to indicate whether link()ing 
should be avoided: The constructor in Base.pm could set a default, 
allowing links, and any subclass that needed to could change it. Then 
the line in ACTION_distclean() could be changed to pass the appropriate 
flag to manicopy() based on the config option???

I've tried a few times to reproduce the problem with the system() call, 
but have been unsuccessfull. I'm sure I have run through the tests a few 
thousand times (using scripts, not manually ;) using various compilers 
and version of perl and this has never resurfaced, so I think it 
unlikely it will come up again; I just wish I knew from whence it came 
and to whither it went.
