Ok, I've looked deeper into it. You are right, that in the tarballs the
enable-more-warnings flag is off per default. But in the following
packages the *.spec.in files add it explicitly to the configure command
line: oaf, gnome-vfs, nautilus, medusa.

However, you mentioned, that my setup is wrong. Well, compiling oaf
with --enable-more-warnings gives me the following error:

gcc -DHAVE_CONFIG_H -I. -I. -I.. -I.. -I.. -I../liboaf -I../liboaf

So obviously it has nothing to do with oaf directly, but with my setup. My
libc version is 2.1.3 which contains /usr/include/bits/string2.h. I assume
you don't get this error, so what libc version are you using?
