I figured it out. I have to specify the libraries AFTER my objects.
Why does the order matter?
Also ... why does the example in the fact (apparently from msp430-gcc
-v) link in libgcc twice?

Subject: Multiplier errors when invoking ld directly
The FAQ says:
>>I am getting link errors about missing multiply routines. What is
wrong?
>The usual cause for this problem is that you specified a different
"-mmcu=" option at the compile and link stages.
For invoking ld directly, the above probably means "-m emulation".
I pass this to ld:
-m msp430x149
-nostdlib
-L/mspgcc/msp430/lib
-L/mspgcc/lib/gcc-lib/msp430/3.2.3
-lc -lm -lgcc
I think those are the only libraries I should need, but those symbosl
are indeed not there. I did objdumps on every library in the toolsuite
and didn't find ANY of the symbols it is looking for ... __udivmodsi4
__umulsi3hw etc.
If I am linking explicitly with LD, where do I find these objects?
