Your kernel limits the data section of your programs to $maxdsiz Mb,
which is (sadly) not enough to fully optimize some parts of the

those parts. If you are a sysadmin, and you *do* want full
optimization, raise the 'maxdsiz' kernel configuration parameter
to at least 0x08000000 (128 Mb) and rebuild your kernel.
