You have three trailing underscores instead of two here. :-)
Could you look at the list of the predefined macros and see what it
contains? From memory, you need to do something like
touch empty.cpp
g++ -m32 -march=i386 -dM -E empty.cpp
I've never seen g++ not define __i386__ with -march=i386. Very odd.
