Duh.  I don't know how many times I looked right past sun4 and saw sun4-os3.

Anyway, now that I have gcc built for the correct os, I am still getting the
same problem I had before.  Namely, when I call inet_ntoa() I sometimes get
core dumps.  I used a debugger to find that I was indeed getting a SEGV in
inet_ntoa() and that the correct value was being passed.  If I write a small
test program, it works fine.  If I compile the source for inet_ntoa() myself
and link it in (rather than using the library)  it works fine.

struct sockaddr_in foo;
inet_ntoa(foo.sin_addr);

What's gives?
