It's glibc practice (although missing from 
<https://sourceware.org/glibc/wiki/Style_and_Conventions>) that we *don't* 
add initializations like that to avoid warnings.  If necessary we may use 
the DIAG_* macros with appropriate comments about why the warning is a 
false positive (sometimes other approaches work to avoid the warnings, 
e.g. use of __builtin_unreachable () calls).
