URGENT code review request for Win* UnhandledExceptionFilter fix (6918421)

[Daniel D. Daugherty]

Greetings,

I have an urgent code review request for a Win* fix. Basically,
I'm making a minor tweak to Ivan's original fix for the following
bug:

    6550813 5/3 Crash because of FPU control word being modified
                by native code (win32)

Here's the URL for my tweak:

    http://cr.openjdk.java.net/~dcubed/6918421-webrev/0/

The fix passes the customer test attached to 6918421 and
it passes the test associated with Ivan's fix for 6550813.

I'm targeting this fix for HSX-17-B09; since this is a P1 it
will be backported to JDK6-UNN...

Thanks, in advance, for any reviews.

Dan
