Aha!  I just found the source of many gcc3 headaches :o)

/usr/local/include has a number of headers (installed by ports) which
test for __FreeBSD__.  In this case the c code was pulling in one of
those headers (from cdparanoia) and of course the test failed.
I just went thru /usr/local/include/ and changed all the __FreeBSD__
references to __DragonFly__ and the port compiled perfectly.
