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!
