--- Comment #2 from Georg-Johann Lay <gjl at gcc dot gnu.org> ---
I cannot reproduce this, neither with v13, v14 nor with v15.
Maybe the preprocessed source as required for a PR gives you some clues.
util/delay.h is provided by AVR-LibC, so maybe you are using a broken /
misconfigured toolchain. For example, you are using a configure command that's
not supported since configuring anywhere in the source tree is not supported
according to https://gcc.gnu.org/install/configure.html
So what you can try is to do is a fresh build with clean sources, clean build
dir and clean install dir for Binutils, GCC and AVR-LibC, e.g somewhere in your
home folder where you do not need root access.
Also as you are configuring AVR-LibC, make sure it is using the expected
compiler, and make sure the configure output for "checking whether avr-gcc
supports __builtin_avr_delay_cycles" matches the expectations.
Maybe it has to do with the linker (plugin) invocation and you get hints
reading the output with -v -Wl,-v
