Hi,
In few dissectors we're manually disabling some kind of warnings, like
in packet-parlay.c
#ifdef _MSC_VER
/* disable warning: "unreference local variable" */
#pragma warning(disable:4101)
#endif
It's possible to do the same with GCC (4.6) using diagnostics pragmas[1].
Googling around found test:
#if __GNUC__ > 4 || (__GNUC__ == 4 && (__GNUC_MINOR__ >= 6 || __APPLE_CC__))
# pragma GCC diagnostic ignored "-Wunused"
#endif
which seems to be not working with my clang-3.3.
qemu does test during configure, trying to compile some test program with -Werror.
I think we could do the same, test program can looks like this:
#v+
#pragma GCC diagnostic push
#pragma GCC diagnostic ignored "-Wunused"
#pragma GCC diagnostic pop
int main(void) {
return 0;
}
#v-
OK?
