Re: [avr-gcc-list] ATTiniy 167 / Float

[Erwan MARC]

we can't change target because of function not available on bigger chips 
(LIN module on ATTiny 167)
the solution we can use at the moment if fix-decimal method, hacking 
library or rewriting  it is not a good solution in my point of view: I 
prefer using validated tools by developers or community than recoding 
everything.

PS: resent to list, instead of direct talking.
