Attached is a patch for hello.c. Thanks Eric, that's much cleaner. I installed it.
the gnulib module exit, to ensure the existence of EXIT_SUCCESS. Isn't it part of some sufficiently-old standard so that it's not necessary/recommended? Solaris release that didn't support atexit has already passed end-of-life. Glad to hear it. Also, you may want to get rid of the space-tab formatting errors in your Ok, I tried. (The world would be an easier place if tools and people considered all whitespace equivalent as the Supreme Hacker originally intended. :) Best, Karl
