It's simply because the distro which I'm using doesn't provide more
recent version of gcc as a package. However I still don't make up my
mind to change the distro to something else because according to the
roadmap of the distro, its new version would be released next month
or next year. In addition I guess It would be difficult to find out a
distro which is available on the machine with memory as small as 128MB :)

I tried this option.
My gcc looks like it understands -Werror option, and as a result,
the following error occurred:
eina_hash.c: In function `_eina_hash_rbtree_each':
eina_hash.c:242: warning: dereferencing type-punned pointer will break
strict-aliasing rules
