Ok, I was mis-remembering the dates when I started at Cygnus Solutions
(forgetting the Open Software Foundation period).  Lets see, I started at
Cygnus in December of 1994, which would mean my initial work on Power to
convert the AIX abi to System V.4/eabi would have started in early 1995.
Looking at eabi.h which was added when I started the System V/eABI work, it was
added in 1995.

It looks like the date listed that Richard Kenner contributed the rs6000.c file
was 1991.  So, while I wasn't involved with Power/PowerPC at the time, it is
fairly close to the 1990 date I mentioned.  According to wikipedia, the first
Power1 (i.e. rs/6000) were introduced in February 1990.
