7186278: Build error after CR#6995781 / 7151532 with GCC 4.7.0

[Takao, Shinji]

Hi All,

It seems that the Yasumasa's patch has employed in:
hg: hsx/hotspot-rt/hotspot: 7186278: Build error after CR#6995781 /7151532 with GCC 4.7.0
http://hg.openjdk.java.net/hsx/hotspot-rt/hotspot/rev/5e2dc722e70d

Although that may be a simply modification, I feel odd that there is no name of Yasumasa
in the ChangeSet...

I am glad if you consider him a contributor. :-)

Thanks,
Shinji
