c++locale.h definitely still exists:
$ find /usr/lib/gcc -name c++locale.h
/usr/lib/gcc/x86_64-pc-linux-gnu/4.6.3/include/g++-v4/x86_64-pc-linux-gnu/32/bits/c++locale.h
/usr/lib/gcc/x86_64-pc-linux-gnu/4.6.3/include/g++-v4/x86_64-pc-linux-gnu/bits/c++locale.h
/usr/lib/gcc/x86_64-pc-linux-gnu/4.7.1/include/g++-v4/x86_64-pc-linux-gnu/32/bits/c++locale.h
/usr/lib/gcc/x86_64-pc-linux-gnu/4.7.1/include/g++-v4/x86_64-pc-linux-gnu/bits/c++locale.h
--disable-nls causes that subversion/svn_private_config.h defines gettext() and dgettext() macros.
If libintl.h was somewhere included, then compilation failure would still occur:
$ cat test.cpp
#define gettext(x) (x)
#define dgettext(domain, x) (x)
#include <libintl.h>
$ g++ -c test.cpp

Build system of GCC creates bits/c++locale.h from libstdc++-v3/config/locale/gnu/c_locale.h on GNU systems and
from libstdc++-v3/config/locale/generic/c_locale.h on other systems (e.g. FreeBSD).
GCC r124803 [1] deleted inclusion of libintl.h in bits/c++locale.h on GNU systems.
This change was released in GCC 4.3.0 [2] and was never backported to gcc-4_2-branch branch [3].

We need to decide if we support GCC <4.3.0 on GNU systems.
