Question is... why is the only > thing affected is make world? It doesn't make sense. This stuff happens. Back in the Dawn of Time, I was helping a colleague debug a problem in a full-screen text editor he was developing. Every time he issued the command to move point to a specific line number, point moved to the end of the file. Other than that, everything (everything!) worked fine. It turned out that his system was running one of the new, 6 MHz Z80 CPUs, and if you hit the CPU chip with a blast of freon, the problem disappeared for a few minutes. Hardware problems can manifest in some really weird ways, and overclocking should be done only by those who have much more time than money. Jim Shankland Flying Fox Computer Systems, Inc.
