This simplifies maintenance, since it makes for just one implementation of each function, letting the compiler have the fun of optimization. In practice this works well nowadays with GCC. E.g., c_isascii might need only three instructions even though the source code lists every ASCII character individually in a large switch statement. Also, fix some z/OS porting bugs reported by Daniel Richard G. in: http://lists.gnu.org/archive/html/bug-gnulib/2015-09/msg00037.html * NEWS: Document the API change. * lib/c-ctype.c: Drastically simplify, since this now just expands inline functions. * lib/c-ctype.h: Use _GL_INLINE_HEADER_BEGIN, _GL_INLINE_HEADER_END. (C_CTYPE_INLINE): New macro. (C_CTYPE_CONSECUTIVE_DIGITS, C_CTYPE_CONSECUTIVE_LOWERCASE) (C_CTYPE_CONSECUTIVE_UPPERCASE): Remove. Verify that either ASCII or EBCDIC is being used. (_C_CTYPE_SIGNED_EBCDIC, _C_CTYPE_CNTRL, _C_CTYPE_A_THRU_F_N) (_C_CTYPE_DIGIT_N, _C_CTYPE_LOWER_N, _C_CTYPE_UPPER_N) (_C_CTYPE_CASES, _C_CTYPE_A_THRU_F, _C_CTYPE_DIGIT, _C_CTYPE_LOWER) (_C_CTYPE_UPPER, _C_CTYPE_PUNCT_PLAIN): New private macros. (_C_CTYPE_CNTRL): In EBCDIC, '\x07' is a control, not '\xff'. (c_isalnum, c_isalpha, c_isascii, c_isblank, c_iscntrl, c_isdigit) (c_isgraph, c_islower, c_isprint, c_ispunct, c_isspace, c_isupper) (c_isxdigit, c_tolower, c_toupper): Now inline functions. (c_tolower, c_toupper): When converting, return the unsigned char, as that is what z/OS does. * lib/c-strcaseeq.h (CASEEQ): Simplify in the light of the removal of some c-ctype.h macros. * modules/c-ctype (Depends-on): Add extern-inline; remove verify. * tests/test-c-ctype.c (test_all): Fix test for c_toupper and c_tolower promotion to be compatible with z/OS.
