a gcc -Wall warning if the user mistakenly passes a 'char' instead

of an int containing an 'unsigned char'. Note that the sizeof will

always be 1, which is what we want for mapping EOF to __CTYPE_PTR[0];

the use of a raw index inside the sizeof triggers the gcc warning if

__c was of type char, and sizeof masks side effects of the extra __c.

Meanwhile, the real index to __CTYPE_PTR+1 must be cast to int,

since isalpha(0x100000001LL) must equal isalpha(1), rather than being

an out-of-bounds reference on a 64-bit machine. */
