RM is one of the variables that should be pre-initialized by Make, and AFAIK should be used to increase portability (well, it's likely not important for QEMU since we require a posix-shell like built environment anyway). According to the info page of Make, chapter "10.3 Variables Used by Implicit Rules": `RM' Command to remove a file; default `rm -f'. I've also checked it again and "make clean" works fine here (using GNU Make 3.82). Which version of Make (and Linux distro) are you using? Anyway, maybe I also simply missed something, so I'm certainly also fine with the patch to revert it to "rm -f". Thomas
