* regex.c: Fix problems when DEBUG is defined.
(extract_number, extract_number_and_incr): Define regardless of whether DEBUG is defined; that's simpler and makes the code less likely to go stale in the normal case when DEBUG is not defined. Return int rather than taking an int * arg. All callers changed. (DEBUG_PRINT1, DEBUG_PRINT2, DEBUG_PRINT3, DEBUG_PRINT4): Remove, replacing with ... (DEBUG_PRINT): New macro. All callers changed. (DEBUG_COMPILES_ARGUMENTS): New macro. (print_fastmap, print_partial_compiled_pattern) [DEBUG]: (print_compiled_pattern, print_double_string) [DEBUG]: Use prototype rather than old-style definition. (print_partial_compiled_pattern, print_compiled_pattern) [DEBUG]: (ENSURE_FAIL_STACK, PUSH_FAILURE_REG) [DEBUG]: (POP_FAILURE_REG_OR_COUNT, PUSH_FAILURE_POINT) [DEBUG]: (POP_FAILURE_POINT, re_match_2_internal) [DEBUG]: Don't assume ptrdiff_t, size_t, and long are the same width as int. (POINTER_TO_OFFSET): Return ptrdiff_t, not regoff_t. This matters only when DEBUG is defined.
