[krbdev.mit.edu #5859] Build of windows/identity fails in clean directory

[Kevin Koch via RT]

The VS2003 build environment still works.  It is the VS2005 
environment that doesn't.  Also, mkdir a\b\c\d creates the entire path 
when run from the VS2005 command window.  I'll bet the difference is 
in the environment perl sets up for sys.  How can I investigate this?  
[Does perl do different things for sys and backtick?]
