[Joerg Wunsch]

Follow-up Comment #3, bug #32086 (project avr-libc):

> I attached a demo project with makefile to test it for you!

Not very helpful.  I already wrote that I cannot reproduce it,
but if you don't believe it:

address@hidden 86% gmake
rm -rf *.o demo.elf *.eps *.png *.pdf *.bak 
rm -rf *.lst *.map *.hex *.bin *.srec
avr-g++ -g -Wall -Os -mmcu=attiny861    -c -o demo.o demo.c
avr-g++ -g -Wall -Os -mmcu=attiny861  -v -Wl,-Map,demo.map -o demo.elf demo.o
-lm
Using built-in specs.
