13 Portability problems not fixed by Gnulib:
16 On some old platforms (Sequent), @code{utime (file, NULL)} fails to set the
17 file's timestamp to the current time.
19 On some platforms, this function mis-handles trailing slash:
22 This function cannot set full timestamp resolution. Use
23 @code{utimensat(AT_FDCWD,file,times,0)}, or the gnulib module utimens,
26 On some platforms, the prototype for @code{utime} omits @code{const}
27 for the second argument. Fortunately, the argument is not modified,
28 so it is safe to cast away const:
