Yes. From reading section 4.13:

	E[0-9A-Z].*     macros in errno.h
	is[a-z].*       externals, ctype.h
	to[a-z].*       externals, ctype.h
	LC_[A-Z].*      macros in locale.h
	<func>f         <func> is any function defined in math.h
	<func>l         <func> is any function defined in math.h
	SIG[A-Z].*      macros in signal.h
	SIG_[A-Z].*     macros in signal.h
	str[a-z].*      externals, stdlib.h and string.h
	mem[a-z].*      externals, string.h
	wcs[a-z].*      externals, string.h

No doubt there are others scattered throughout the spec, but I
haven't the will to go hunting for them.

Can you say "name space pollution"?

Good!
