If we use newlib the isdigit (and other similar functions) return an
error as char can possibly be viewed as signed:
usr/include/ctype.h:57:54: error: array subscript has type ‘char’ [-Werror=char-subscripts]
#define __ctype_lookup(__c) ((__ctype_ptr__+sizeof(""[__c]))[(int)(__c)])
Explicity cast to unsigned char so we deal with both this warning and
possible warning when -Wpointer-sign is enabled.
