I *do* understand that changing IFS will affect the program, but the patch I sent will backup IFS and then restore it; perhaps you missed the backup/restore bits: + local_ifs="$IFS" [...] + IFS=: [...] + IFS="$local_ifs" + return 0 [...] + IFS="$local_ifs" + return 1 Do you have an example of how that breaks if IFS isn't ever set in ./configure at all? -- Loïc Minier
