This is perfectly legal.
See http://pubs.opengroup.org/onlinepubs/9699919799/functions/basename.html

   text   data    bss    dec    hex filename
    165      0      0    165     a5 libc/string/__xpg_basename.os
    113      0      0    113     71 libc/string/__xpg_basename.os.orig

Since the current behaviour is in accordance to the standard and your version
is way bigger i prefer to keep it as is.

Thanks anyway!
