  Modified:    lib/libc/i386/sys  brk.S
  Log:
  Fixed comparisons so that preposterously large (>= 0x80000000) brk values
  aren't silently converted to minbrk.  This stops malloc(INT_MAX) from
  dumping core.  Small values are still silently converted.  They should
  be an error.  sbrk() doesn't do any range checking or conversions or
  overflow checking.
  
  Moved PIC_EPILOGUE invocation to a more natural place where it
  obviously doesn't interfere with the comparison.
