[Sun-spots readers: hatstat is a program Sun is sending out for sites
wishing to test whether they need the PMEG patches or not.  Apparently,
just about everyone needs the PMEG patches!]

You can modify one line in hatstat.c and it will continue to work after
you install the pmeg patches.  Here is the patch:

*** hatstat.c   Fri Nov  9 18:02:49 1990
--- hat41.c     Fri Nov  9 18:31:40 1990
***************
*** 27,31 ****
  struct nlist nl[] = {
  #define       N_HATCNT        0
!       { "_hatcnt" },
  #define       N_PMGRPFREE     1
        { "_pmgrpfree" },
--- 27,31 ----
  struct nlist nl[] = {
  #define       N_HATCNT        0
!       { "_cnt" },
  #define       N_PMGRPFREE     1
        { "_pmgrpfree" },

Apparently, the _hatcnt function has been renamed as _cnt in the vm_hat.o
that comes with the pmeg patches.  Note that I don't have SunOS 4.1.1
sources, so I can't really verify this.  I just ran strings on the kernel
modules and grepped around a bit.

But after applying the patch above and recompiling, the hatstat program
continues to run.

Hope this helps.
