The problems I saw was some random failures in the gcc test suite.  I 
have not analyzed the failures in details, but I do not expect them to be 
serious; it is probably just some special cases where gcc forget to 
honor TARGET_96_ROUND_53_LONG_DOUBLE while optimizing (and a couple of the 
failures are due to incorrect test cases that assume that "everything
work as Linux"...)

I plan to fix this before gcc 4.3 is released...
