I found out there's a whole set of extra stuff needed.  I had to add all 
the below:

-lmikmod -lpthread -lsmpeg -lwsock32 -ldxguid -lvorbisfile -lvorbis -logg

The application links, but doesn't run in Windows (exits immediately 
when double clicking).  In Wine, it hangs indefinitely with:

err:ntdll:RtlpWaitForCriticalSection section 0x11ad510 "?" wait timed 
out in thread 0009, blocked by 0000, retrying (60 sec)

messages.

But I guess this is an SDL problem, not mingw's fault.
