cc65/include/errno.h
Christian Groessler 94ba9575ec Implement exec() for Atari XDOS.
- Adds new ENOEXEC error code, also used by Apple2 targets.
- Maximum command line length is 40, incl. program name. This is
  an XDOS restriction.
- testcode/lib/tinyshell.c has been extended to be able to run
  programs.
