+ Use functions, not macros, for up- and down-casing (Bug#8254).
+ * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
+ (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
+ to use the following functions instead of these macros.
+ (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
+ EMACS_INT, since callers assume the returned value fits in int.
+ (upcase1): Likewise, for UPCASE_TABLE.
+ (uppercasep, lowercasep, upcase): New static inline functions.
+
* regex.c (CHARSET_LOOKUP_RANGE_TABLE_RAW, POP_FAILURE_REG_OR_COUNT):
Rename locals to avoid shadowing.
(regex_compile, re_match_2_internal): Move locals to avoid shadowing.
