This isn't a bug in m4 or anything architecture-specific, it's a regression that was introduced by an upstream change in glibc [1] and mainly affects qemu-user which we are using for m68k and sh4 [2]. While the change in glibc is most certainly correct (I don't have enough background knowledge to comment on that), it broke qemu-user for everyone and so far there is no possible fix in sight. I am CC'ing this to libc-alpha in the hope that someone from glibc upstream might give us a tip on how to resolve the issue. Not being able to use qemu-user anymore is quite a deal breaker because lots of people use qemu-user for debugging issues on foreign architectures which is now no longer possible. Thanks, Adrian
