Thanks for the response!

I *was* using "gcc file.cpp" as I've done for years for C++ and C source, 
but after seeing your message, I tried using g++ instead, and it linked 
okay. Is this some sort of GCC 2.9x vs 3.X thing? I've always relied on gcc 
to properly determine what to do based on file extension. Is it not 
supposed to do that any more, or is this breakage?

-v shows the only difference to be during the ld step (as you'd expect). 
Here's the g++ (working) version:

ld -dc -dp -e __start -dynamic-linker /usr/libexec/ld.elf_so 
/usr/lib/crt0.o /usr/lib/crti.o /usr/lib/crtbegin.o \
-L/usr/bin/../libexec /var/tmp//ccKnyxsd.o -lstdc++ -lm -lgcc_s -lgcc -lc 
-lgcc_s -lgcc \
/usr/lib/crtend.o /usr/lib/crtn.o

and here's the gcc (non-working) version:

ld -dc -dp -e __start -dynamic-linker /usr/libexec/ld.elf_so 
/usr/lib/crt0.o /usr/lib/crti.o /usr/lib/crtbegin.o \
-L/usr/bin/../libexec /var/tmp//ccOxeMXe.o -lgcc -lgcc_eh -lc -lgcc 
-lgcc_eh /usr/lib/crtend.o /usr/lib/crtn.o
