Summary: Using float arithmetic without linking with -lm result in incorrect
code
Original Submission: In the normal C environment, it's possibile to compile
correct code using floating point arithmetic without linking math library. Math
library is required only if functions like sin() are used. I try to do the same
with avr-libc, but the math code included (__floatsisf for instance) contains
jmp 0x0 wich obviusly isn't what I wanted. Linking with -lm is a solution, but
it must be stated that every use of FPA requires -lm.
