5.5 and groups of preprocessing

[lovewar]

such as

Code:

#ifndef NO_TAG
static void log (const char *format, ...)
{
}
#else
#if defined(__STDC_VERSION__)
#define log(...) do { } while (0)    // here
#endif
#endif

and, the identifier(log) exists after preprocssing has been performed:

Code:

static void log (const char *format, ...)   // does it apply to #define log ?
{
}

I have a question regarding rule 5.5: does the function(log) apply to #define log ?

Rule 5.5 amplification states that

name of macros that exist prior to preprocessing

be distinct from

identifiers that exist after preprocessing.

Prior to preprocessing there is a macro called "log".

If the code is compiled when NO_TAG is not defined, the code after preprocessing will include a function identifier "log". Under these circumstances, there is a violation of rule 5.5.
