Log Message:
lint: fix handling of initializations
The implementation from March 2021 added proper support for designators
but didn't model the brace levels correctly. In particular, it could
not handle additional braces or omitted braces. In such a case, lint
skipped the remaining initializers from the initialization. Due to
this, type errors in the remaining initializers went unnoticed. Another
effect was that arrays of unknown size were wrongly reported as having
size 0.
Both GCC and Clang recommend placing braces around each sub-type that is
initialized, such as a struct, union or array. Postfix does not follow
these recommendations, therefore lint had to be disabled in
external/ibm-public/postfix/Makefile.inc. This commit fixes the bugs
mentioned there.
