[avr-libc-dev] avr/iousbxx6_7.h: INT0_vect versus SIG_INTERRUPT0

for most parts, all Interrupts have two defines, one as XXX_vect and the
another as SIG_XXXY, like for /iom128.h
/* External Interrupt Request 0 */
#define INT0_vect_num                   1
#define INT0_vect                       _VECTOR(1)
#define SIG_INTERRUPT0                  _VECTOR(1)

But even in avr-libc-1.8.0, for all parts including
iousbxx6_7.h like the at90usb1287, only  XXX_vect is defined:
/* External Interrupt Request 0 */
#define INT0_vect_num                   1
#define INT0_vect                       _VECTOR(1)

Is this intentional? Or would a patch defining all those SIG_XXXY be

E.g. the Ethernut sources reference only SIG_XXXY and so for support of
at90usb1287 either iousbxx6_7.h needs changes or the etehrnut sources.
