-Wunused-local-typedefs -Wsizeof-pointer-memaccess build warnings

[Raghavendra D Prabhu]

Seeing many warnings of the following type:

-Wunused-local-typedefs
-Wsizeof-pointer-memaccess

Full log here http://paste.wnohang.net/1a5446

[Raghavendra D Prabhu (raghavendra-prabhu)]

To add, this is with gcc 4.8.0.

Raghu -

Almost all if not all of these warnings are in the upstream code, so please report it there on their sources. Setting to Incomplete until then.

This will become a problem once some platform we support starts using GCC 4.8 by default, and the upstream will have the same issue and presumably will fix.

[Raghavendra D Prabhu (raghavendra-prabhu)]

Ack, I will report it upstream as well after I build from it.
Regarding platform, yeah, gcc 4.8 is not part of our supported
platforms but I reported because I presumed there may be bugs in
the code highlighted by them, but they may all be false positives
as well.

Ubuntu 13.10 now has GCC 4.8 by default.
