RE: [avr-libc-dev] 64-bit doubles

I have implemented for AVRs the 32-bit single precision and 64-bit double
precision floating point types from John Hauser's SoftFloat package
http://www.jhauser.us/arithmetic/SoftFloat.html. This is a full IEC/IEEE
implementation and provides all arithmetic functions including square root.

While it works very well indeed, the library takes nearly 63K using -Os.
There would be much work to do reducing this to something manageable. So I
have decided to use an AVR32 and the marvellous free Atmel tools for the
original project, starting after a week or so of serious sun and surf. 

Sorry about not carrying this through. I can zip up the project if anyone is
