<cctype> and namespace std

[Roman Belenov]

Hello,

<cctype> from libstdc++ puts symbols like 'toupper' to namespace
std. Does standard actually require it ? Latest public draft says
nothing about it (it specifies that the content of files like <cctype>
should be identical to correspondent C header with some changes, but
nothing is said about namespaces).

PS Sorry for not asking first in comp.std.c++, my connection to Usenet
is rather poor.
