Hi Ahmad,

Ah - I was going by the comment in libiberty.h:

  /* Return a temporary file name or NULL if unable to create one.  */

  extern char *make_temp_file (const char *) ATTRIBUTE_MALLOC;

And the libiberty info documentation:

  -- Replacement: char* make_temp_file (const char *SUFFIX)

     Return a temporary file name (as a string) or 'NULL' if unable to
     create one.  SUFFIX is a suffix to append to the file name.  The
     string is 'malloc'ed, and the temporary file has been created.

I guess that the header file and documentation are out of date.
