Defect Report #079

1. If a pointer to a given standard library function (say strlen) is evaluated in two different translation units, and the pointers compared, must they compare equal?
2. Can a conforming implementation declare a standard library function as having internal linkage, or must the identifiers with file scope declared in standard headers have external linkage?
3. If the contents of the header <string.h> include the following definition of strlen, is the implementation conforming?
   static size_t strlen (const char *__s)
   {
   size_t __len = 0;
   
   while (*__s++)
   __len++;
   return __len;
   }
