  Gnulib module: execve
  
  Portability problems fixed by Gnulib:
  @itemize
  @item
  On Windows platforms (excluding Cygwin), this function does not pass
  command-line arguments correctly if they contain space, tab, backslash,
  or double-quote characters.
  @item
  On Windows platforms (excluding Cygwin), this function spawns an asynchronous
  child process and then exits the current process immediately.  As a
  consequence, the parent of the current process 1. may incorrectly proceed
  as if its child had exited, and 2. will never see the child's exit status.
  @item
  On Windows platforms (excluding Cygwin), the return type of this function is
  @code{intptr_t}, not @code{int}.
  @end itemize
  
  Note: The Gnulib replacement for this function is not async-safe, that is,
  it must not be invoked from a signal handler.
  
  Portability problems not fixed by Gnulib:
  @itemize
  @item
  On some platforms, a script without executable permission is still run:
  Cygwin 1.5.x.
  @end itemize
