Dumb, I setenv'ed on one window and tried it in another. Decided it
should have been done that way, so I suggested it. Aren't I prescient?
What about installing the man pages for ld, which now conflict aout vs.
elf, as ld-aout and ld-elf? Then setting maybe a softlink based upon
the objformat, from ld to the real one? I've been caching away the
ld-aout man page, to get at it.
