I use make and I don't ignore it. But if I have two solutions for a C code: 1. use #include 2. use make to physically insert the same piece of code into several source files before compiling them the result is the same. However I prefer the first solution ;-) It's getting off-topic. Thanks for the information on pipemap . I didn't noticed it. Best regards, Marek
