Title: #378: [RFC] Use GNULIB's compiler warning code
I did not review all the patches, but I do not like the removal of the INI warning. I
guess we can not treat warnings as errors for all platforms. It is easy to forget that you
need new ding-libs for some of the features to work properly in SSSD and if someone
compiles the code for EL6 (scratch builds) this warning is a valuable piece of
information. I explicitly grep for it when do some scratch builds to verify if the new
ding-libs was available during compile time (not just run time).
