.. 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
checking whether compiler handles -Wuninitialized... yes
checking whether compiler handles -Werror=sequence-point... yes
checking whether compiler handles -Wunused-parameter... yes
checking whether compiler handles -fno-common... yes
checking whether compiler handles -Wunused-result... no
checking whether compiler handles -Wmissing-prototypes... yes
checking whether compiler handles -Wunused-variable... yes
checking whether compiler handles -Wmissing-parameter-type... no
checking whether compiler handles -Wunused-but-set-parameter... no
checking whether compiler handles -Wunused-but-set-variable... no
checking whether compiler handles -Wredundant-decls... 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.
