New description:

 The Windows cmd interpreter badly handles )'s in rem statements,
 *sometimes* (but not always) closing "if" statements they are nested
 within. Per docs, parens are illegal in rem commands (see
 technet.microsoft.com/en-us/library/bb490986.aspx).

 On my Win7 64bit box, this was causing bootstrap vc12 to go down bizarre
 paths. One potential fix is to escape the parens, i.e. use !^( and !^)
 instead of () in comments. I wish I were making this up (sigh).
