Subject: Ignore -Waddress for alsaaudio.c
X-Git-Tag: v0.11.0-rc1~34
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=6f40c941bd9782fec6af7759f031b49b939009b1;p=thirdparty%2Fqemu.git

Ignore -Waddress for alsaaudio.c

/usr/include/alsa/pcm.h contains:

#define snd_pcm_sw_params_alloca(ptr) do { assert(ptr); *ptr = (snd_pcm_sw_params_t *) alloca(snd_pcm_sw_params_sizeof()); memset(*ptr, 0, snd_pcm_sw_params_sizeof()); } while (0)

The assert generates: "error: the address of 'sw_params' will always
evaluate as 'true'" which combined with -Werror prevents alsaaudio.o
from being built with certain versions of GCC.
