>From info '(libc)Error Messages', about program_invocation_name and program_invocation_short_name: *Portability Note:* These two variables are GNU extensions. If you want your program to work with non-GNU libraries, you must save the value of `argv[0]' in `main', and then strip off the directory names yourself. We added these extensions to make it possible to write self-contained error-reporting subroutines that require no explicit cooperation from `main'. This suggests that making global parameters available only as arguments of main would be a bad idea. But they should be settable, to account for the rare case of wanting to substitute something else to a library which reads them itself. -- __("< Marcin Kowalczyk \__/ [EMAIL PROTECTED] ^^ http://qrnik.knm.org.pl/~qrczak/ _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
