Win32 Debug Break

[Michael D. Pritchett]

Using cygwin and CLI the debug build has been broken.  I was able to trace
the error to new code in ut_assert.h.

Using the command line CLI _MSC_VER is not defined.  As a result the new
thread-safe <crtdbg.h> somehow clashes with stdlib.h and the build fails.  I
am uncertain how to get <crtdbg.h> to work.

Cheers!
