Add debug options to print recipes even if they would otherwise be silent, and to print the reason that a target was considered out of date. Modify --trace to simply be a shorthand for --debug=print,why. * NEWS: Announce changes. * doc/make.texi (Summary of Options): Document the new options. * doc/make.1: Ditto. * src/debug.h: Add new flags DB_PRINT and DB_WHY. * src/makeint.h: Remove the trace_flag variable. * src/job.c (start_job_command): Check debug flags not trace_flag. (new_job): Ditto. * src/main.c (trace_flag): Make a static variable for switches. (decode_debug_flags): Set DB_PRINT and DB_WHY if trace_flag is set. * tests/scripts/variables/GNUMAKEFLAGS: Update known-good messages. * tests/scripts/variables/MAKEFLAGS: Ditto.
