Hooray!!

Perhaps something along the lines of:

(putting the "#ifdef _LP64" back in, of course.)

(and varargs.h (or stuff in stdarg.h) is deprecated? Can't remember --
wasn't necessary to delete or modify these files, however.)

This change worked rather well for me.  Compiled all of 1.6P userland
except for the compiler itself, and anything that required c++
(groff).  Seems to work.

Hope this helps.  Hope it's not too simplistic.  If you've something
for me to test, I'll try.
