jdk7u full build fails on Win - unable to load zip.dll

[Pete Brunet]

A full 7u build currently fails like this:

Error occurred during initialization of VM
Unable to load ZIP library:
C:\Users\Pete\JDK7u\jdk7-clone\jdk7\build\windows-i586-fastdebug\bin\zip.dll

I have BUILD_DEPLOY and BUILD_INSTALL set to off.  I mention that
because this was advice much earlier when hitting the same problem.

Any ideas?
