+ * src/nice.c (GET_NICE_VALUE): Renamed from GET_PRIORITY.
+ All uses changed.
+ (NZERO): New macro, if system doesn't define it already.
+ (usage): Distinguish priorities from nice values.
+ Don't assume NZERO is 20.
+ (main): Use bool instead of int where appropriate.
+ If user specifies an adjustment out of range, always truncate it
+ to an inrange value instead of sometimes giving an error message
+ and sometimes not.
+ Do not assume that -1 is an error return from "nice" or
+ "getpriority", as it might be the current nice value minus NZERO.
+ If nice/setpriority fails with errno == EPERM, go ahead and run
+ the command anyway; POSIX requires this.
+
* src/pathchk.c: Include euidaccess.h.
(dir_ok): Use euidaccess, not access.
* src/test.c (R_OK, W_OK, X_OK, FOK): Remove; system.h defines them.
