Thanks for the initial work. I tracked it down to m4_shiftn(2, sequence of two elements) causing an infinite loop from _UTIL_CHECK_SYSCALL in configure.ac. For some reason the optimized version m4_shift2 introduced in autoconf 2.62 (very old version) does not suffer from this issue. Also note that the relevant configure.ac code got completely rewritten on the path to 2.24 and probably does not suffer this issue. I assume that a new upstream release would fix this FTBFS as well. In addition a new upstream release is kinda required to fix other RC bugs of util-linux. Should I NMU the attached patch to util-linux? Helmut
