I don't know about that bug.  Rn has worked just fine for me after I made some
patches to:
1)  Use struct dirent instead of struct direct, and include <dirent.h>;
2)  Undefine the references to "char *sprintf()" and "int *(signal())";
3)  Comment out tokens after #else and #endif statements (not necessary for
    compilation, I just don't like _any_ compiler messages!); and
4)  Add the line "char *CD, *CM, *HO;" to term.c, and an "extern" version
    to any other modules that need it.

I recall reading some caveats in the release notes, but do not remember them
off the top of my head (I'll look 'em up on Tuesday when I get back to work).

Hi folks,

     If anybody has code that they *know* breaks this optimizer,
I would be much appreciative if you would pass it along to me.  I
know a little bit about this program and may be able to help, but
in any case am very interested in any bug reports you might be
able to provide to me on this.

     Just for fun, here are a couple of debug options that you
might wish to play with:

        cc -# {args}           show execution of each part of the compile

        cc -W2,-s {args}       send optim stats to stderr

        cc -W2,-z {args}       send inline-expansion stats to stderr

     Steve
