What is your glibc version?
%m appears to be supported since 2.7
But if possible we would like perf to be buildable on most
boxes. May be should we use %a instead there.
odd gcc versions will whine because of the confusion with the %a for
floating point things but that can be worked around with (float *) casts (sigh).
Well, since we also have strict aliasing checks, we'll actually need:
scanf("%a", (float *)(void *)str);
We do that in util/trace-event-parse.c
