Hi,
the latest compilers (gcc 4.9 and clang 3.4) issue warnings when doing 
an incomplete struct initialization (e.g. "struct tc_sizespec s = 
{0};").

Since many people like to compile lower level bits and pieces with 
-Werror, this should probably be fixed. Patch attached.

Sounds like newer compilers are reverting:

Hopefully not.

thanks,

Patch

From: Bernhard Rosenkränzer <Bernhard.Rosenkranzer@linaro.org>
Subject: [PATCH] Fix compiler warnings with gcc 4.9 and clang 3.4

Current compilers (gcc 4.9 and clang 3.4) issue warnings when doing
an incomplete struct initialization (e.g. "struct tc_sizespec s = {0};").

Initialize the structs completely so we can build with -Werror.
