+
+ * dep.h (dep): Add the DONTCARE bitfield.
+
+ * filedef.h (file):Add the NO_DIAG bitfield.
+
+ * read.c (eval_makefile): Set the DONTCARE flag in struct dep,
+ not struct file (a file can be a dependency of many targets,
+ some don't care, some do).
+
+ * remake.c (update_goal_chain): Propagate DONTCARE from struct
+ dep to struct file before updating the goal and restore it
+ afterwards.
+ (update_file): Don't prune the dependency graph if this target
+ has failed but the diagnostics hasn't been issued.
+ (complain): Scan the file's dependency graph to find the file
+ that caused the failure.
+ (update_file_1): Use NO_DIAG instead of DONTCARE to decide
+ whether to print diagnostics.
+
+ Fixes Savannah bugs #15110, #25493, #12686, and #17740.
