Follow-up Comment #2, bug #29458 (project avr-libc):
Hello Joerg,
It seems a link error. The attached Studio4 screendump show the folowing
message:
rm -rf FloatTest.o FloatTest.elf dep/* FloatTest.hex
FloatTest.eep FloatTest.lss FloatTest.map
Build succeeded with 0 Warnings...

I compile with Studio4, I do not know how to add the -ml option.
