Subject: build: disable warnings on cast alignments
X-Git-Tag: 1.0.5~53

build: disable warnings on cast alignments

clang is often wront about it (it increases alignment requirement, but
the surrounding structure ensure the alignment is correct). Dunno if
gcc is smarter or just ignore most of these problems.
