-slang: change char type to signed char in macros
-
-C language has 3 distinct char types:
- char
- unsigned char
- signed char
-A char has the same range of values as signed char on X86,
-but same as unsigned char on ARM which made Slang's typecast()
-and array_sort() unable to work for char value on ARM, since
-Slang is assuming "char" as "signed char".
-
-Now we change "char" as "signed char" explicitly in
-util/mkslarith2.sl, and use it to regenerate src/slarith2.inc
