From 9466071bf2165b7201029ca40ac8673f5ce3761a Mon Sep 17 00:00:00 2001 From: Jim Meyering Date: Wed, 26 Apr 1995 17:18:27 +0000 Subject: [PATCH] (REGEX_FREE): Define to `while (0) /* empty */' rather than nothing. Otherwise, some uses got warnings about empty if-clause. Declare failure_stack_ptr only #ifdef REL_ALLOC. --- lib/regex.c | 6 +++++- 1 file changed, 5 insertions(+), 1 deletion(-) diff --git a/lib/regex.c b/lib/regex.c index e275c3b7c..7cb8da8b1 100644 --- a/lib/regex.c +++ b/lib/regex.c @@ -240,7 +240,7 @@ char *alloca (); destination) /* No need to do anything to free, after alloca. */ -#define REGEX_FREE(arg) +#define REGEX_FREE(arg) while (0) /* empty */ #endif /* not REGEX_MALLOC */ @@ -2857,9 +2857,11 @@ re_compile_fastmap (bufp) unsigned char *p = pattern; register unsigned char *pend = pattern + size; +#ifdef REL_ALLOC /* This holds the pointer to the failure stack, when it is allocated relocatably. */ fail_stack_elt_t *failure_stack_ptr; +#endif /* Assume that each path through the pattern can be null until proven otherwise.
