Return to dump.h CVS log

Up to [local] / src / usr.bin / make

more changes, discussed and tested by various people.
- 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.
