--- Comment #5 from Eduardo Abinader <eduardo.abinader at openbossa dot org> ---
This new macro ATTRIBUTE_RETURNS_NONNULL should work ok for gcc 4.8.2? I am
having problems including libiberty.h in ubuntu 14.04. 

/usr/include/libiberty/libiberty.h: In function ‘basename’:
/usr/include/libiberty/libiberty.h:110:38: error: expected declaration
specifiers before ‘ATTRIBUTE_RETURNS_NONNULL’
 extern char *basename (const char *) ATTRIBUTE_RETURNS_NONNULL
ATTRIBUTE_NONNULL(1); 
  /usr/include/libiberty/libiberty.h:121:45: error: expected ‘=’, ‘,’, ‘;’,
‘asm’ or ‘__attribute__’ before ‘ATTRIBUTE_RETURNS_NONNULL’
 extern const char *lbasename (const char *) ATTRIBUTE_RETURNS_NONNULL
ATTRIBUTE_NONNULL(1); 
                                             ^
/usr/include/libiberty/libiberty.h:126:49: error: expected ‘=’, ‘,’, ‘;’, ‘asm’
or ‘__attribute__’ before ‘ATTRIBUTE_RETURNS_NONNULL’
 extern const char *dos_lbasename (const char *) ATTRIBUTE_RETURNS_NONNULL
ATTRIBUTE_NONNULL(1);
                                                 ^
/usr/include/libiberty/libiberty.h:132:50: error: expected ‘=’, ‘,’, ‘;’, ‘asm’
or ‘__attribute__’ before ‘ATTRIBUTE_RETURNS_NONNULL’
 extern const char *unix_lbasename (const char *) ATTRIBUTE_RETURNS_NONNULL
ATTRIBUTE_NONNULL(1);
...

they seem to face the same problem:
