Thank you for correcting my oversight.  I did not mean to slight Denis
by not mentioning his excellent contribution to this whole avr-gcc
effort.  I was merely wanted to thank those who gave me specific detail
that got me off dead-center and moving forward.  Sometimes when one is
new to a subject, they need a small push in the right direction to get
going.  Thanks again for that push!

This sounds like a challenge. ;-)  I can't say I'm up to it, mainly
because I found out yesterday, that I'm going to be gainfully employed
again (for at least about 300 hours) contracting to my old employer -
from whom I took early retirement two years ago.  I do programming on
mainframes (HP3000 and HP-UX) and from time to time on PC's (MS Access,
Visual Basic, Excel Macros, etc.)  That employment will keep me busy for
a while.  My "play time" will be devoted to learning Java for using
Dallas Semi's 1-wire iButton products for some Renewable Energy
applications I want to explore.  And, lastly, I'm NOT a fan of the C
language.  That in itself is a major challenge to me!  But, as you can
see, I'm still attempting to learn ;-)

Now, you have piqued my curiosity, Joerg.  Keep us informed on your
progress.  I've always wanted to build a "crystal replacement" for
rock-bound rigs, such as commercial two-way radios that are cheaply had
at swapfests.  A few years back I looked into Qualcomm's efforts with
their DDS chip, but did not pursue it.
