Really?  Could you give an example?

That is perfectly legal C (since "forever"?) and I find it more readable
than memset.  Don't treat it as a request to keep the original version -
if I were Pavan I would object this particular request since I prefer
direct initialization, however here I'm more interested in learning more
about your statement about compilers not supporting zero initialization
of array members after the last initializer.  And maybe also about to
what extent we should be supporting old/non compliant compilers (the doc
suggest to use gcc 4.9+).

Best regards
