Hi,


There's a bug in the new character class tables for Windows and ISO
charsets.

To support signed chars, the tables for the negative values -128..-1 are
identical to the values of the positive values 128..255.  Many of these
character sets have a valid character at the position 255.  So some
functions return a non-0 value not only for the unsigned char value 255,
but also for the equivalent signed char value -1.  Unfortunately this
potentially breaks applications which use the EOF value as argument to
the ctype functions.  They expect that the functions always return 0,
but in the current implementation they don't.

The below patch fixes that.  It splits off the value for char 255 from the
rest of the definition, so that the actual character class tables can
return another value for the unsigned char value 255 than for -1.

For instance, the former definition for the ISO-8859-1 table looked
like this:

    { _CTYPE_ISO_8859_1_128_256,
      _CTYPE_DATA_0_127,
      _CTYPE_ISO_8859_1_128_256
    },

The new definition now looks like this:

    { _CTYPE_ISO_8859_1_128_254,
      0,
      _CTYPE_DATA_0_127,
      _CTYPE_ISO_8859_1_128_254,
      _CTYPE_ISO_8859_1_255
    },

While I was at it I also took the liberty to rename _CTYPE_DATA_128_256
to _CTYPE_DATA_128_255, which is more correct since the definitions contains
the character values 128..255, not 128..256.

Ok the apply?

Yes, please go ahead.

Thanks,

* libc/ctype/ctype_.c (_CTYPE_DATA_128_255): Rename from _CTYPE_DATA_128_256. * libc/ctype/ctype_cp.h: Split off all character class values for character 255 from the rest of the definitions. (__ctype_cp): Use the new definitions. Make sure that the table always contains 0 for EOF (-1). * libc/ctype/ctype_iso.h: Ditto.
