That's a good idea. I'll try to do so. One thing I'm afraid
is how stable each size of data types between different compiler
versions. I hope these are not changed so frequently.

Right! I misunderstand what --host means and what --target means.

One last problem in kaffe-0.10.1 with dynamic linking is that
there are no definition for 'ld' command (which should also be
ld for cross development environment) in configure file. So,
I have to modify Makefile's to make shared library. It can be
fixed to include something like
	AC_CHECK_TOOL(LD, ld)
in configure.in file.

In case of kaffe-0.9.2 similar treatment is needed to find
proper assembler.
