Compiling libc with -O2, then compiling df with it yields output like this: Filesystem Size Used Avail Capacity Mounted on /dev/da0s1a 252M <5M :7M 54% / devfs 1.0K 1.0K 0B :0% /dev /dev/da0s1f 3.2G 2.2G 757M 75% /usr /dev/da0s1e 252M 28M 204M <% /var procfs 4.0K 4.0K 0B :0% /proc linprocfs 4.0K 4.0K 0B :0% The system gcc3 and all versions of gcc3 in our ports do this. gcc295 does not.
