I take it that's <pseudocode>
FUNCTION_LIKE_MACRO(early, args,
#ifdef SYMBOL
symbol,
#else
token,
#endif
remaining);
</pseudocode> which is indeed not supported by ANSI C:
<quote src="ANSI X3.159-1989, 3.8.3 Macro Replacement, closing words">
If there are sequences of preprocessing tokens within the list of
arguments that would otherwise act as preprocessing directives, the
behavior is undefined.
</quote>
It should be easy to fix this; the usual pattern turns the above into
#ifdef SYMBOL
FUNCTION_LIKE_MACRO(early, args, symbol, remaining);
#else
FUNCTION_LIKE_MACRO(early, args, token, remaining);
#endif
which is entirely legitimate.
