isxdigit() macro definition is the same. isalnum() from linux/ctype.h will accept additional latin non-ASCII characters. This is harmless since this macro is used in scanhex() which parses user input.
isspace() from linux/ctype.h will accept vertical tab and form feed but not NULL. The use of this macro is modified to accept NULL as well. Additional characters are harmless since this macro is also only used in scanhex().
