* libc/ctype/ctype_.c: When compiled with gcc on platforms
with signed char, make _ctype_[-128] ... _ctype[-1] refer to
initialized memory region. Platform can define COMPACT_CTYPE
to avoid allocation of the additional 128 bytes of data.
Add pointer to _ctype_ array. Always initialize all _ctype_
array elements.
