  Modified:    lib/msun/src  s_rint.c s_rintf.c
  Log:
  Made rintf() actually work.  It was completely broken (when s_rint.c
  was compiled with -O) by the precision bug in the i386 version of
  gcc (assignments and casts don't clip the precision).  E.g.,
  rintf(12.3456789) was 12.125.
  
  Avoid the same bug in rint().  It was only broken for the unusual
  case when the i387 precision is 64 bits.  FreeBSD defaults to 53
  bit precision to avoid problems like this, but the standard math
  emulator always uses 64 bit precision.
