Aw, I see, my code broken. I got confused by locale_......_asign()
family
if functions. Sure, first argument need to be int. But as you said the
code
is a wart.

If we go this way why not make a special case only and only for 'I'
Character and not all 7-bit ASCII:
unsigned char ch = (unsigned char) ident[i];
if(ch == (unsigned char)'I')
ch = 'i';
else
ch = tolower(ch)
ident[i] = (char) ch;
Will it break any locales?
