Portability problems not fixed by Gnulib:
@itemize
@item
On Windows platforms (excluding Cygwin), the command processor used by the
@code{system} function is @file{cmd.exe}, not @file{/bin/sh}.  Accordingly,
the rules for quoting shell arguments containing spaces, quote or other special
characters are different.
