This is somewhat of an artificial example.

$ uname -r 
5.6
$ cat foo.c
int main() { return(0); }
$ /usr/ccs/bin/make foo
cc    -o foo foo.c 
$ ./foo

Now, on another machine:

$ uname -r
5.8
$ ./foo
$ rm foo
$ /usr/ccs/bin/make foo
cc    -o foo foo.c 
$ ./foo

Back on the first machine, after recompiling
foo on Solaris 8:

$ ./foo

But it does show that what you said about compiled programs
being neither forward nor backward compatible doesn't apply
without at least some qualification.
