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.

Hack up the C library and/or compiler? Or implement your own floating point 
library and avoid native float types and operators. Or switch to a beefier

yes it is.
Is there any solution to reduce size of this area?
we have been working on "fix decimal" solution and are close to to a solution but may have to switch again to float in the future.

PS for Jörg, I'll check if we have the option -lm or not, what is the impact?

It's probably scratch area for software floating point library, since avr has no fpu.
