[cmucl-cvs] CMUCL commit: cross-sol-x86-branch src/lisp (solaris-os.c)

[Raymond Toy]

    Date: Monday, December 20, 2010 @ 17:11:53
  Author: rtoy
    Path: /project/cmucl/cvsroot/src/lisp
     Tag: cross-sol-x86-branch

Modified: solaris-os.c

o Fix a compiler warning.
o Get the correct data from the x87 FPU state for the control and
  status words.  Unfortunately, it looks as if Solaris/x86 doesn't
  save the x87 state in the sigcontext.
