Tidy up signal handling. All signal() calls have been changed to pending_signal() calls. pending_signal() is defined in the new sig.c file. It remembers the handler and traps the signal with a function that will remember the signal. main.c now calls handle_signals() to actually call the required handlers (if the above handler was called). If this doesn't close PR2662 (was PR2347), I'll cry. Joerg, I think this should go into 2.2, but I havn't done anything about it because I'm bound to botch it with the new sig.[ch] files. I've just "cvs add"'d sig.[ch] so far.... can you update to 2.2 and tell me what you did ? Thanks.
