Browse Source 
Fix the following build failure with gcc 4.8 raised since bump to
version 2.86 in commit 5b29096f8f:

pattern.c: In function 'is_valid_dns_name':
pattern.c:134:3: error: 'for' loop initial declarations are only allowed in C99 mode
   for (const char *c = value;; c++)
   ^
pattern.c:134:3: note: use option -std=c99 or -std=gnu99 to compile your code
pattern.c: In function 'is_valid_dns_name_pattern':
pattern.c:249:3: error: 'for' loop initial declarations are only allowed in C99 mode
   for (const char *c = value;; c++)
   ^
