Wow.   You did a really good job wordsmithing my text.   Thanx!   I have
exactly zero comments on the words you emitted.

I believe that to be true only to the Fortran crowd.  (Insert joke about
several blind men looking at an elephant here.)  Other languages -
especially for embedded targets - have been multilibbed for some time.
I'm quite sure I was using multilibbed embedded MIPS targets in the
middle of the decade becuase I remember cursing how long they took to
build on my Sparc Classic. :-)

I'm even more sure that GCC 2.8.0 had multilib support for OpenServer
and that Kean and I cribbed the support in '96 from other existing
multilibbed targets.  So I think this particular feature isn't new.

None of this changes the motivation for including the documentation,
