 ==================================================================
 Looking down into libiberty.h, I picked on basename()

 /* HAVE_DECL_* is a three-state macro: undefined, 0 or 1.  If it is
    undefined, we haven't run the autoconf check so provide the
    declaration without arguments.  If it is 0, we checked and failed
    to find the declaration so provide a fully prototyped one.  If it
    is 1, we found it so don't provide any declaration at all.  */
 #if !HAVE_DECL_BASENAME
 #if defined (__GNU_LIBRARY__ ) || defined (__linux__) \
  || defined (__FreeBSD__) || defined (__OpenBSD__) || defined (__NetBSD__)
 \
  || defined (__CYGWIN__) || defined (__CYGWIN32__) || defined
 (__MINGW32__) \
  || defined (__DragonFly__) || defined (HAVE_DECL_BASENAME)
 extern char *basename (const char *) ATTRIBUTE_RETURNS_NONNULL
 ATTRIBUTE_NONNULL(1);
 #else
 /* Do not allow basename to be used if there is no prototype seen.  We
    either need to use the above prototype or have one from
    autoconf which would result in HAVE_DECL_BASENAME being set.  */
 #define basename basename_cannot_be_used_without_a_prototype
 #endif
 #endif
 ============================================
 The native CentOS 7 has this definition of basename:

 # ifndef basename
 /* Return the file name within directory of FILENAME.  We don't
    declare the function if the `basename' macro is available (defined
    in <libgen.h>) which makes the XPG version of this function
    available.  */
 #  ifdef __CORRECT_ISO_CPP_STRING_H_PROTO
 extern "C++" char *basename (char *__filename)
      __THROW __asm ("basename") __nonnull ((1));
 extern "C++" const char *basename (const char *__filename)
      __THROW __asm ("basename") __nonnull ((1));
 #  else
 extern char *basename (const char *__filename) __THROW __nonnull ((1));
 #  endif
 # endif
 #endif

 ==============================
 I think we are getting the C++ prototype from string.h and a conflicting C
 prototype from libiberty.h
