+ Portability fixes:
+ * #include <fcntl.h>, not <sys/fcntl.h> (fixes some implicit decls).
+ * Look for gmd5sum. (Thanks to Anton Altaparmakov for the report.)
+ * install-sh updated to that from autoconf 2.53.
+ * Use fcntl F_{GET,SET}FD with respect for as-yet-uninvented fd flags.
+ (small patch from Ben Harris.)
+
+ Documentation and help improvements:
+ * userv(1) manpage: fixed broken definitions of fd excl and trunc.
+ (Debian bug report: Closes: #79579.)
+ * Specification's usage notes section improved.
+ * --help and --version behaviour made to conform to GNU standards.
