 .. I spent hour to improve UL_WARN_ADD and after commit and push I
 found that whole problem could be resolved by an extra -Werror in
 UL_WARN_ADD implementation.

 so the result from CC=clang ./configure is:

checking whether compiler handles -Wextra... yes
checking whether compiler handles -Wno-missing-field-initializers... yes
checking whether compiler handles -Wsign-compare... yes
checking whether compiler handles -Wtype-limits... yes

 Why we need this if code is compiled with -Wno-missing-field-initializers?

 It's pretty obvious in C standard how are missing fields are initialized
 in global and static variables.
