C99 is only $20 from ANSI.
C99 section 7.1.4, paragraph 1:
7.1.4 Use of library functions
1 Each of the following statements applies unless explicitly stated
otherwise in the detailed descriptions that follow:
[...]
Any function declared in a header may be additionally implemented as a
function-like macro defined in the header, so if a library function is
declared explicitly when its header is included, one of the techniques
shown below can be used to ensure the declaration is not affected by
such a macro.
