__intel_avx_rep_memset not defined

When running with gcc 4.8.3 headers installed, and icc 16.0.0, I get the the following error when using memset.  I'm running this on Fedora 20.  On Fedora 22, this error doesn't appear (possibly because that's gcc 5 headers, but I don't really know where the problem is comping from.

[bradley@30-87-232 intel]$ cat avxmemset.c
#include <string.h>

double v[1000];

int main() {
    memset(v, 0, sizeof(v));
    return 0;
}
