[libvoikko] [PATCH] libvoikko: Fix build with GCC 4.6

[Ville-Pekka Vainio]

I my mail software doesn't break the patch... Fedora recently switched
to GCC 4.6 in Fedora 15 and building libvoikko 3.1 with it causes this
warning, which is treated as an error:

morphology/malaga/values.cpp: In function 'void
libvoikko::morphology::malaga::build_path(libvoikko::morphology::malaga::int_t, libvoikko::morphology::malaga::MalagaState*)':
morphology/malaga/values.cpp:1219:24: error: variable 'element_end' set
but not used [-Werror=unused-but-set-variable]

The following patch fixes the problem.
