Commit log from Dragonfly:

Browse source 
FreeBSD extended ctypes to include numbers (e.g. isnumber()) but never
actually implemented it.  The isnumber() function was equivalent to the
isdigit() function in every case.

Now that DragonFly's ctype source files have number definitions, the
number ctype can finally be implemented.  It's given a new flag _CTYPE_N.
The isalnum() and iswalnum() functions have been changed to use this
flag rather than the _CTYPE_D digit flag.

While isalnum(), isnumber(), and their wide equivalents now return
different values in locale cases, the ishexnumber() and iswhexnumber()
functions are unchanged.  They are still aliases for isxdigit() and
iswxdigit().

Also change ctype.h for isdigit and isxdigit to use sbistype like the
other functions.
