The article is wonderful, but the following question still remains. How do I
merge trees taken from, let's say, gcc-2.95.2, binutils-2.10, and newlib-1.8.2
distributions together? What to do with 'include' and 'libiberty' directories
in this case? Take them from the latest distribution, or what?

Actually, I took everything from binutils, then 'gcc' directory from gcc, then 
'newlib' directory from newlib. This seems to work, but is it the right thing
to do?

Thanks in advance.
