- put back some job control, turns out it's necessary when we don't run a shell. - zap old #ifdef CLEANUP code... probably doesn't even compile. - kill most of the OP_LIB code. Just keep a wee little bit for compatibility (deprecated .LIBS and .INCLUDES, warns for weird dependencies instead of erroring out). - much improved debugging and -p output: sort variables, targets, rules, output stuff in a nicer format mimicing input. - better error message when no command is found, explain where the target comes from. - sort final error list by file. - show system files in errors as <bsd.prog.mk> - reincorporate random delay, that was dropped - optimize siginfo output by not regenerating the whole string each time. - finish zapping old LocationInfo field that's no longer used.
