Not directly when it talks about <ctype.h>, but in section 7.1.7 when it
talks about 'Use of Library functions':
Any function declared in a header may be additionally implemented
as a macro defined in the header ... The user of #undef to
remove any macro definition will also ensure that that an actual
function is referred to.
So no, it doesn't say that you should do this with macros, but if you
do you _must_ provided a functional equivalent (so you can take the
address of it), and the header file _must_ declare this function. I
dont remember seeing the function definitions in the header file...

Actually, there is a patch in Terry Lambert's patchkit Alpha-3 that fixes
this...
