Subject: [PATCH] Remove dummy structure declarations for old buggy compilers.
|
|
|
|
While woolly mammoths still roamed the Earth and before Atlantis
|
|
sunk into the ocean, there were C compilers that could not handle
|
|
forward structure references, e.g. "struct name;". zlib dutifully
|
|
provided a work-around for such compilers. That work-around is no
|
|
longer needed, and, per the recommendation of a security audit of
|
|
the zlib code by Trail of Bits and TrustInSoft, in support of the
|
|
Mozilla Foundation, should be removed since what a compiler will
|
|
do with this is technically undefined. From the report: "there is
|
|
no telling what interactions the bug could have in the future with
|
|
link-time optimizations and type-based alias analyses, both
|
|
features that are present (but not default) in clang."
