512 - 1023 of the first 2048 byte sector on a CD.
On hppa we plopped down such a disklabel on cdXX.iso and installXX.iso.
Once accessible it took precedence over the spoofed label of the CD. Chaos
ensued. Since there is currently no reason for this label on hppa
cd's, eradicate it and its disktab entry. cdXX.iso/installXX.iso can now
be mounted on hppa again.
Also remove a commented out label plopping on Alpha, which references a
non-existant disktab entry.

remains.

extensions: __real__ and __imag__ operators, the use of '~' for
complex conjugation, and 'i' or 'j' as a suffix for complex constants.
While this doesn't handle folding and overflow detection for complex
constants correctly, it's good enough to make it through libm...and
found several bugs once it could do so.
