It doesn't even need to be anything compilable. For example, you could generate "*.2" files from "*.1" files by "cp", generate "*.3" files from multiple "*.2" files by "cat". Once you have a simple sample case like that, post the makefile here and people can try to help. This particular newsgroup has been ruined years ago by one of the worst scourges of Usenet, "Amine Ramdane". But there are still sane people lurking here who would welcome a change from that crackpot - so please give us a nice challenge here!
