[Konstantin Belousov]

Author: kib
Date: Wed Feb 17 09:09:12 2010
New Revision: 203989
URL: http://svn.freebsd.org/changeset/base/203989

Log:
  MFC r203441:
  Placate new binutils, by using 16-bit %ax instead of 32-bit %eax as an
  argument for fnstsw. Explicitely specify sizes for the XMM control and
  status word and X87 control and status words.
