Wow :/ makedepend is even more broken than I thought.

This patch breaks doxygen, so I'd rather not take it if possible...

You'll want to do:
CFLAGS='-m32 -O2 -g -gdwarf-2' CXXFLAGS='-m32 -O2 -g -gdwarf-2'
./autogen.sh .... --enable-32-bit

(you need -m32 and you need to set CXXFLAGS).  Then it should work.
