FWIW, here is the set of warnings I see when building with gcc (GCC)
4.9.0 20131204 (experimental) on x86_64 and i686:


 grep 'warning: ' ../build/make.LOG
../locale/weightwc.h:88:7: warning: *((void *)&str+4) may be used
uninitialized in this function [-Wmaybe-uninitialized]

Building tests does generate a lot more ...
