That's good news.  Thanks for working on this.

I think we can fix this problem by using the mkstemp function that
gnulib provides.  Or, you can try modifying this code in
src/file-io.cc:

  #if defined (HAVE_MKSTEMPS)
  // Prototype for mkstemps in libiberty
  extern "C" int mkstemps (char *pattern, int suffix_len);
  #endif

  #if ! defined (HAVE_MKSTEMP) && ! defined (HAVE_MKSTEMPS) && defined 
(_MSC_VER)
  # if defined (HAVE_FCNTL_H)
  #  include <fcntl.h>
  # endif
  # if defined (HAVE_SYS_STAT_H)
  #  include <sys/stat.h>
  # endif
  int mkstemp (char *tmpl)
  {
    int ret=-1;
    mktemp (tmpl);
    ret = open (tmpl, O_RDWR | O_BINARY | O_CREAT | O_EXCL | _O_SHORT_LIVED,
                _S_IREAD | _S_IWRITE);
    return ret;
  }
  #define HAVE_MKSTEMP 1
  #endif

I don't see why it should be restricted to just _MSC_VER.  It looks to
me like it should work on any system that has the open system call and
all the needed O_x, _O_x, and _S_x macros defined.

At what point in the build process did this error occur?
