[Bug-gnulib] readtokens bug

[Bruno Haible]

Hi Jim,

I made this patch. It avoids a crash on 64-bit platforms, when one of the
delimiters is a non-ASCII byte. ( remember (unsigned char) -5 = 0xFB but
(unsigned int) -5 = 0x00000000FFFFFFFB) )

        * readtokens.c (readtoken): Cast character to 'unsigned char', not
        'unsigned int'.
