Portability problems fixed by Gnulib:

Portability problems not fixed by Gnulib:

• On some old platforms (Sequent), utime (file, NULL) fails to set the file's timestamp to the current time.
• On some platforms, this function mis-handles trailing slash: Solaris 9.
• This function cannot set full timestamp resolution. Use utimensat(AT_FDCWD,file,times,0), or the gnulib module utimens, instead.
• On some platforms, the prototype for utime omits const for the second argument. Fortunately, the argument is not modified, so it is safe to cast away const: mingw, MSVC 9.
